1 00:00:01,459 --> 00:00:11,460 Okay, so today we are going to continue talking about the views of Anocted. 2 00:00:11,460 --> 00:00:19,460 I'm going to use the web page you already know. 3 00:00:19,460 --> 00:00:28,629 I'm going to use this one because I want to explain something. 4 00:00:28,629 --> 00:00:31,629 I'm not going to do an exercise. 5 00:00:31,629 --> 00:00:40,630 it's just to help to help myself to describe the ideas okay I'm going to 6 00:00:40,630 --> 00:00:47,729 follow the PDF here in the virtual classroom there's a PDF the theory okay 7 00:00:47,729 --> 00:00:53,750 we already we already have the task you did the other day and it's correction 8 00:00:53,750 --> 00:01:00,670 and we are going to spend a little bit this PDF this theory okay I want to talk 9 00:01:00,670 --> 00:01:07,950 about the views of an object. What are they, the views of an object? They are the different 10 00:01:07,950 --> 00:01:14,549 ways we have to visualize an object. For example, if I'm looking at the object this way, I have 11 00:01:14,549 --> 00:01:20,290 a view. If I'm looking at the object this way, I have a view. If I'm looking at the 12 00:01:20,290 --> 00:01:30,290 object this way, I have a view. These are, you have the definition here, views are the 13 00:01:30,290 --> 00:01:34,909 different ways we can visualize an object. This is the key word. Different ways we can 14 00:01:34,909 --> 00:01:43,909 visualize an object, ok? How many views are there? What do you think? You can answer in 15 00:01:43,909 --> 00:01:59,230 the chat, using the chat. 1, 2, 3, 4, 5, 6, 7, how many? 3, 3. I have 2 answers. 3, 3, 16 00:01:59,230 --> 00:02:03,230 All of you think that there are three views. 17 00:02:03,230 --> 00:02:07,230 Why three? I think you are answering three because 18 00:02:07,230 --> 00:02:11,229 the other day we drew three views. But 19 00:02:11,229 --> 00:02:15,229 I'm going to use this one. Ok. This is a view. 20 00:02:15,229 --> 00:02:19,229 This is a view. And this is a view. 21 00:02:19,229 --> 00:02:23,229 These are the three ones and we studied the previous day. But 22 00:02:23,229 --> 00:02:27,229 what happens about this one? Is this a view? What do you think? 23 00:02:27,229 --> 00:02:33,590 are more, but we are with three. John Grant. 24 00:02:33,689 --> 00:02:37,169 Okay, so you think that there are more than three. Yes. So, this 25 00:02:37,169 --> 00:02:41,830 okay, Diego, Paula, Lucas, all of you, you agree 26 00:02:41,830 --> 00:02:44,569 that this is a view. And what about this one? This is a view two. 27 00:02:45,349 --> 00:02:49,810 And what about, I cannot rotate the 28 00:02:49,810 --> 00:02:51,789 object more than that. What about this one? 29 00:02:53,509 --> 00:02:56,689 This one in the middle, between the front and the side view. Is this a view? 30 00:02:56,689 --> 00:03:02,240 yes, it is, yes, yes, so all of you 31 00:03:02,240 --> 00:03:06,520 you agree that there are more than 3 views, how many views are there? 32 00:03:07,620 --> 00:03:13,219 6 views, ok, Chloe 33 00:03:13,219 --> 00:03:17,340 maybe you think that we have the 4, I mean the top view, infinite, infinite 34 00:03:17,340 --> 00:03:21,340 Victoria says infinite, 5, 6 35 00:03:21,340 --> 00:03:24,639 infinite, I think that 6, 4 36 00:03:24,639 --> 00:03:29,319 I don't know, ok, a lot of answers, the idea is that there are 37 00:03:29,319 --> 00:03:33,199 infinite views. For instance, this one is a view. 38 00:03:33,800 --> 00:03:36,860 It's the front view. What happens if I move it a little bit? 39 00:03:37,039 --> 00:03:39,759 It's different. It's not the front view. 40 00:03:41,159 --> 00:03:43,699 It's similar to the front view, but it's not the front view. 41 00:03:44,560 --> 00:03:47,919 So, it's a different one. What happens if I move it a little bit 42 00:03:47,919 --> 00:03:51,680 more? It's not the same than before. It's a new one. What happens 43 00:03:51,680 --> 00:03:55,340 if I move it a little bit more? It's not the same 44 00:03:55,340 --> 00:03:59,340 one than before. It's a new one. What happens if I move a little bit? 45 00:03:59,759 --> 00:04:03,520 So, there are infinite views. The moment I move the object 46 00:04:03,520 --> 00:04:06,599 a little bit, I have a new one. A little bit, I have a new one. 47 00:04:07,379 --> 00:04:09,680 So, and how many 48 00:04:09,680 --> 00:04:15,159 infinite views are there? I mean, how many little bits are there? 49 00:04:15,539 --> 00:04:18,000 Infinite. So, we have infinite views. 50 00:04:18,800 --> 00:04:22,540 This is the first thing we need to take into account. There are infinite views. 51 00:04:22,540 --> 00:04:35,529 and what the purpose of the views why do we need views you don't know because if 52 00:04:35,529 --> 00:04:43,389 I have a 3d object for instance for instance for instance this one I want to 53 00:04:43,389 --> 00:04:51,689 I'm sharing my screen imagine have this one the keys of my car there are 54 00:04:51,689 --> 00:05:02,129 infinite views of it, ok? But what are the purpose of them? This is a 3D object, do 55 00:05:02,129 --> 00:05:08,850 you agree? I hope so. The idea is that if I want to send information about this 56 00:05:08,850 --> 00:05:17,550 one to you, you are looking at it using a screen. How many dimensions can you find 57 00:05:17,550 --> 00:05:21,610 in the screen. What do you think? I'm going to open the chat 58 00:05:21,610 --> 00:05:25,069 again. How many dimensions are there on the screen? Four. 59 00:05:25,449 --> 00:05:31,480 Four dimensions. How many 60 00:05:31,480 --> 00:05:35,860 dimensions are on your screen? Here. You are looking at my keys, the keys of my 61 00:05:35,860 --> 00:05:39,300 car. How many dimensions are on the screen? Three? No. 62 00:05:40,800 --> 00:05:42,459 Two. Two dimensions. 63 00:05:43,220 --> 00:05:50,689 The long and the height. 64 00:05:50,689 --> 00:05:54,329 ok, the lung and the eye, two dimensions 65 00:05:54,329 --> 00:05:56,670 no more than that, ok 66 00:05:56,670 --> 00:06:00,370 so, can you guess the problem? 67 00:06:00,610 --> 00:06:02,129 the problem is that I'm 68 00:06:02,129 --> 00:06:10,899 the problem is that I'm trying to represent 69 00:06:10,899 --> 00:06:13,620 a 3D object using two dimensions 70 00:06:13,620 --> 00:06:17,779 can you guess the problem? can you guess what the problem is? 71 00:06:18,459 --> 00:06:21,139 the problem is that I'm losing information 72 00:06:21,139 --> 00:06:25,560 if I have a 3D object and I can only represent 73 00:06:25,560 --> 00:06:29,100 two dimensions, I am losing one dimension 74 00:06:29,100 --> 00:06:33,420 this is the problem, so how can we solve it? 75 00:06:33,860 --> 00:06:37,579 because I am trying to send information to you, I am trying to 76 00:06:37,579 --> 00:06:41,560 describe how my keys are, so the idea 77 00:06:41,560 --> 00:06:45,639 is that I will send, I will show more 78 00:06:45,639 --> 00:06:49,480 than one single view to you, because one single view is not enough 79 00:06:49,480 --> 00:06:53,000 to represent the object. I have infinite views 80 00:06:53,000 --> 00:06:57,680 but sending infinite views is a problem too. I cannot 81 00:06:57,680 --> 00:07:01,740 send infinite views. So, how many views 82 00:07:01,740 --> 00:07:05,800 are enough to give full information of the object? What do you 83 00:07:05,800 --> 00:07:09,920 think? We already know that there are 84 00:07:09,920 --> 00:07:13,579 infinite views. Six. John Pratt says six. 85 00:07:13,740 --> 00:07:24,470 And the other ones, what do you think? No say. I don't know. It's better than no say. 86 00:07:24,470 --> 00:07:33,649 And the rest of you? What do you think? 87 00:07:33,649 --> 00:07:37,649 I don't know, I don't know, I don't know. Okay. Six views 88 00:07:37,649 --> 00:07:41,649 are enough to give enough information, to give full 89 00:07:41,649 --> 00:07:45,649 information about the object. For instance, imagine I want to open 90 00:07:45,649 --> 00:07:52,560 the period. This is the object. Or I also 91 00:07:52,560 --> 00:07:56,560 have the one I opened the previous day. 92 00:07:56,560 --> 00:08:05,720 I want to open it again. Use of an object. 93 00:08:05,720 --> 00:08:13,240 this one is the same idea than this one these are we have the six views of the object 94 00:08:13,240 --> 00:08:21,319 can you look at the guy looking at the object from different positions here in this kind of clouds 95 00:08:21,319 --> 00:08:30,439 we can see what the guy is looking is seeing you can see the view so if using this sixth position 96 00:08:30,439 --> 00:08:34,559 you, I mean, we will be able to see everything about the object. 97 00:08:35,120 --> 00:08:38,440 So, six views are, although there are infinite views, 98 00:08:38,899 --> 00:08:42,519 six views are enough to send all the information 99 00:08:42,519 --> 00:08:46,500 about this object. So, for instance, if I want to send, if I want 100 00:08:46,500 --> 00:08:49,759 to describe this 3D object using a 2D 101 00:08:49,759 --> 00:08:54,580 screen or a 2D sheet 102 00:08:54,580 --> 00:08:58,259 of paper, I will be able to draw these 103 00:08:58,259 --> 00:09:02,539 six views and I will be able to give you the full information 104 00:09:02,539 --> 00:09:06,419 about the object. Okay? So, I repeat, there are infinite views 105 00:09:06,419 --> 00:09:10,080 but six are enough to give all the information to you. Okay? 106 00:09:11,019 --> 00:09:12,639 So, what else? 107 00:09:14,019 --> 00:09:18,480 Let's go back to the theory. So, there are 108 00:09:18,480 --> 00:09:22,559 six views to describe, to give the full 109 00:09:22,559 --> 00:09:26,059 information. They are, the names of them are given 110 00:09:26,059 --> 00:09:30,139 by the position from which we are looking at the object. 111 00:09:30,340 --> 00:09:33,740 If we are looking at the object from the front, we have the front view. 112 00:09:34,179 --> 00:09:37,600 If we are looking at the object from the back, we have the back view, 113 00:09:38,679 --> 00:09:41,840 the same for the top view, the same for the bottom view, 114 00:09:42,259 --> 00:09:45,700 the same for the left side view, the same for the right side view, okay? 115 00:09:50,460 --> 00:09:58,399 And if I want to draw them, I will have to draw them following the idea of the projections, okay? 116 00:09:58,519 --> 00:10:19,019 It means that I will respect some relative positions, and these are the relative positions. What is once? Because of something that I want to open in the virtual classroom, I made a mistake, I'm going to open it now. I'm going to open a video. Let's see if it works. 117 00:10:19,019 --> 00:10:31,720 I thought I had opened it but I didn't. I'm going to open it in one second. 118 00:10:31,720 --> 00:10:49,620 Here video tutorial is one. I'm going to open it. 119 00:10:49,620 --> 00:11:01,169 okay I'm opening and opening it I will go back to my to the student view one 120 00:11:01,169 --> 00:11:10,129 second student now I'm looking at the virtual classroom I can see they look at the virtual 121 00:11:10,129 --> 00:11:14,389 classroom the same way you look at it and now I want to open this video 122 00:11:14,389 --> 00:11:21,450 tutorial let's see if this is the correct one yes it is 123 00:11:26,919 --> 00:11:42,000 I made a mistake. I will try to open it in a different way. 124 00:11:42,000 --> 00:12:13,250 I made a mistake. I didn't open it before, so that's why I made a mistake. 125 00:12:13,250 --> 00:12:38,639 I'm sorry. I will try to open it again. 126 00:12:38,639 --> 00:13:00,100 Ok, I have it, I think I have it. Ok, it's here, I didn't make a mistake. 127 00:13:03,100 --> 00:13:12,100 Ok, I'm sorry, now I have it. This is my object, similar to the one I'm showing to you in www.educacionplastica.net. 128 00:13:13,100 --> 00:13:19,100 So, we are going to draw the different views. Imagine there will be a cube around the object. 129 00:13:23,100 --> 00:13:27,100 Can you see the cube around the object? 130 00:13:27,100 --> 00:13:31,100 So, we are going to draw each view 131 00:13:31,100 --> 00:13:35,100 on the opposite side of the cube. Let's start with, for instance, 132 00:13:35,100 --> 00:13:39,100 the green one. This is the front view. The yellow one 133 00:13:39,100 --> 00:13:43,100 is the front view and is projected, the view is projected on the back. 134 00:13:43,100 --> 00:13:47,100 Can you see it? 135 00:13:47,100 --> 00:13:57,100 The green one is projected, it's the left side view and it's projected on the right side of the cube. 136 00:14:01,100 --> 00:14:02,100 The top view is... 137 00:14:05,100 --> 00:14:13,100 And this is the top view. We are looking at the object from above, but the top view is projected on the bottom side of the cube. 138 00:14:17,100 --> 00:14:32,100 Now we have the three views that have been projected on the sides of the screen. 139 00:14:32,100 --> 00:14:37,100 Now we remove the object that was in the center. 140 00:14:37,100 --> 00:14:45,100 And now we will unfold. Do you understand unfold? Fold is a verb, doblar, unfold, the opposite one, desdoblar. 141 00:14:45,100 --> 00:14:47,100 We will unfold 142 00:14:57,600 --> 00:15:03,919 So if we unfold the cube the front view is in the middle the left side view is on the right and the top view is 143 00:15:04,600 --> 00:15:09,980 On the bottom forget about these walls from the in-hand plan. I don't know what this video is using 144 00:15:10,299 --> 00:15:11,659 but 145 00:15:11,659 --> 00:15:13,659 This is why this is why 146 00:15:13,659 --> 00:15:18,659 This is why... I don't know if there are questions. Yes, no, there are no questions. 147 00:15:18,659 --> 00:15:23,659 This is why when we draw everything on... 148 00:15:23,659 --> 00:15:31,659 When we draw the six views of an object, everything seems to be on the opposite position. 149 00:15:31,659 --> 00:15:35,659 For example, the left side view is on the right, the right side view is on the left, 150 00:15:35,659 --> 00:15:40,659 the top view is on the bottom, and the bottom view is on the top. 151 00:15:40,659 --> 00:15:46,340 back view is here, because these different views have been projected on the different 152 00:15:46,340 --> 00:15:51,659 sides of the object, of the cube, and when we unfold the cube everything seems to be 153 00:15:51,659 --> 00:15:57,460 on the opposite way. And when we draw the different views of an object this is the way 154 00:15:57,460 --> 00:16:04,539 we represent them. That's why in this exercise, the one we did the other day, the front view 155 00:16:04,539 --> 00:16:15,840 was here you remember when i draw the front view i draw it here when i draw the left side view the 156 00:16:15,840 --> 00:16:26,379 blue one i draw it on the right and when i draw the top view i draw it on the bottom that's why 157 00:16:26,379 --> 00:16:33,740 these are the positions to draw everything okay we understand if there is any questions you can 158 00:16:33,740 --> 00:16:38,659 open your microphone or you can write something in there I mean you can write 159 00:16:38,659 --> 00:16:44,539 anything in there I don't understand Jorge Jimenez Romero why what you don't understand 160 00:16:44,539 --> 00:16:54,820 can I talk? yes of course when the video I don't understand very well the 161 00:16:54,820 --> 00:17:02,259 video okay let's explain it step by step we have the object okay do you 162 00:17:02,259 --> 00:17:07,890 Do you agree? Open the micro, both hands, keep it open. 163 00:17:07,890 --> 00:17:11,890 What has to be the object? Do you understand that the object 164 00:17:11,890 --> 00:17:15,890 can be in the middle of a cube? 165 00:17:15,890 --> 00:17:19,890 Yes. Ok, imagine the object and around the object 166 00:17:19,890 --> 00:17:23,890 we have a cube, ok? Ok. 167 00:17:23,890 --> 00:17:27,890 Ok, now we have three views. We are going to 168 00:17:27,890 --> 00:17:31,890 draw just three of them, ok? We have the front view that is the yellow one, 169 00:17:31,890 --> 00:17:36,390 one, the left side view that is the green one and the top view that is the blue one. 170 00:17:36,390 --> 00:17:37,390 Do you agree? 171 00:17:37,390 --> 00:17:38,390 Okay. 172 00:17:38,390 --> 00:17:39,390 Okay. 173 00:17:39,390 --> 00:17:40,390 Yes, yes. 174 00:17:40,390 --> 00:17:48,049 So, we will now the front one that is the yellow one is drawn here on the back of the 175 00:17:48,049 --> 00:17:49,049 cube. 176 00:17:49,049 --> 00:17:55,529 It means it's projected, it's like drawing it and pushing it to the back of the cube. 177 00:17:55,529 --> 00:18:00,890 You draw it and at the same time you push it to the back of the object, do you agree? 178 00:18:00,890 --> 00:18:22,250 Yes, yes. Okay, fine. Now, we do the same for the left side view, the green one. We draw it and we project it on the right. We push it on the right. Do you understand the idea? Easy. Yes, it's easy. We do the same for the top view. 179 00:18:22,250 --> 00:18:26,029 ok, now we have the three of them 180 00:18:26,029 --> 00:18:28,930 we remove the object 181 00:18:28,930 --> 00:18:34,009 and the moment we have removed the object we will unfold 182 00:18:34,009 --> 00:18:36,630 do you understand unfold? I'm going to try it on the chart 183 00:18:36,630 --> 00:18:42,640 unfold is the opposite of fold 184 00:18:42,640 --> 00:18:47,559 fold means doblar, unfold desdoblar 185 00:18:47,559 --> 00:18:51,660 so now we will unfold 186 00:18:51,660 --> 00:19:11,099 We will unfold the video and that's why we have the front view here, the left side view 187 00:19:11,099 --> 00:19:14,380 here and the top view here, do you understand now? 188 00:19:14,380 --> 00:19:22,619 oh okay okay i understand and it's it's not just about their relative positions it's just 189 00:19:22,619 --> 00:19:28,380 it's i mean it's also about keeping the alignment for instance here there is alignment 190 00:19:29,420 --> 00:19:35,259 this one and this one they have the same height they begin at the same position and they finish 191 00:19:35,259 --> 00:19:41,900 at the same position okay you can see that they keep the alignment and the same with the top and 192 00:19:41,900 --> 00:19:49,660 the front view then here they have the same width this much the same width okay we are keeping the 193 00:19:49,660 --> 00:19:59,740 alignment and if i go back to the pdf i was trying to explain that it was here we have the sixth 194 00:19:59,740 --> 00:20:04,700 position but they are keeping the alignment can you see that we are keeping the alignment 195 00:20:04,700 --> 00:20:11,700 I can't understand the thing you said. 196 00:20:11,700 --> 00:20:14,700 What's the problem? 197 00:20:14,700 --> 00:20:17,700 Alignment. 198 00:20:17,700 --> 00:20:20,700 Alignment, what's the meaning of alignment? 199 00:20:20,700 --> 00:20:22,700 In Spanish, I want to write it. 200 00:20:22,700 --> 00:20:26,700 Wait a second, I'm looking for the chat. 201 00:20:26,700 --> 00:20:30,700 Alignment. 202 00:20:30,700 --> 00:20:35,880 I don't think this is the correct spelling 203 00:20:35,880 --> 00:20:39,599 alignment, alignment means alineación 204 00:20:39,599 --> 00:20:43,000 to keep the alignment means that 205 00:20:43,000 --> 00:20:47,849 están alineados, do you agree? 206 00:20:48,450 --> 00:20:51,670 yes, yes, I'm going to check the spelling 207 00:20:51,670 --> 00:20:54,930 but I think it's the correct one 208 00:20:54,930 --> 00:21:04,589 alignment, it was the correct spelling 209 00:21:04,589 --> 00:21:07,750 So, it means that they keep the alignment. 210 00:21:07,930 --> 00:21:09,029 They están alineados. 211 00:21:09,390 --> 00:21:12,289 Can you see that the six views are keeping the alignment? 212 00:21:14,549 --> 00:21:15,509 Oh, yes. 213 00:21:16,230 --> 00:21:18,150 It's not floating here. 214 00:21:18,670 --> 00:21:20,170 This one is not floating here. 215 00:21:20,569 --> 00:21:21,710 They are keeping the alignment. 216 00:21:23,210 --> 00:21:24,190 Están alineados. 217 00:21:24,309 --> 00:21:25,549 And the rest of you, do you understand? 218 00:21:30,099 --> 00:21:35,359 So, it's important when we draw the object, 219 00:21:35,359 --> 00:21:39,640 I mean, when we draw the views, we have to respect the relative positions 220 00:21:39,640 --> 00:21:41,759 and we also have to keep the alignment. 221 00:21:43,220 --> 00:21:46,700 And this is because of the cube. This cube we have unfolded 222 00:21:46,700 --> 00:21:51,619 because this is the idea. We draw the different views of an object 223 00:21:51,619 --> 00:21:55,039 and we push them to the opposite side. And then we unfold the cube 224 00:21:55,039 --> 00:21:59,099 and that's why everything seems to be in the opposite position 225 00:21:59,099 --> 00:22:03,460 but they are not. And that's why they have to keep 226 00:22:03,460 --> 00:22:07,400 there like that, ok? No more questions? 227 00:22:09,400 --> 00:22:11,460 Nobody is writing, so I think there are no more 228 00:22:11,460 --> 00:22:15,539 questions. Let's move on. We have six views 229 00:22:15,539 --> 00:22:19,660 that have six different 230 00:22:19,660 --> 00:22:23,779 projections, ok? But usually, instead 231 00:22:23,779 --> 00:22:27,720 of drawing six views, we will only 232 00:22:27,720 --> 00:22:31,480 draw three of them. Why? Because although 233 00:22:31,480 --> 00:22:35,339 three of them, they don't provide the full information about 234 00:22:35,339 --> 00:22:38,940 the object. They provide enough information. 235 00:22:39,980 --> 00:22:43,299 Okay? Can you see the idea? 236 00:22:43,559 --> 00:22:47,519 Because drawing six views can be a little bit 237 00:22:47,519 --> 00:22:49,819 long. Usually we need to spend 238 00:22:49,819 --> 00:22:55,680 more time than expected to draw the six views. And usually 239 00:22:55,680 --> 00:22:58,279 with three views is enough 240 00:22:58,279 --> 00:23:02,059 to imagine the whole, the object 241 00:23:02,059 --> 00:23:06,440 by itself, ok, so usually we draw just three of them 242 00:23:06,440 --> 00:23:10,460 we are not 100% sure we have the full information 243 00:23:10,460 --> 00:23:12,839 but usually we have enough information 244 00:23:12,839 --> 00:23:22,519 now, here we have the names of the three 245 00:23:22,519 --> 00:23:26,400 dimensions, the names of them are height 246 00:23:26,400 --> 00:23:30,579 in Spanish we say alto, here we have height, we have length 247 00:23:30,579 --> 00:23:34,299 in Spanish we say largo, and we have width, in Spanish we say 248 00:23:34,299 --> 00:23:37,980 ancho, ok, but 249 00:23:37,980 --> 00:23:41,640 which one is the height, which one is the length, which one is the width 250 00:23:41,640 --> 00:23:46,680 interesting questions, or more or less the same question 251 00:23:46,680 --> 00:23:48,660 where is the front view 252 00:23:48,660 --> 00:23:52,380 we need to 253 00:23:52,380 --> 00:23:58,180 we need to decide which one is the front view 254 00:23:58,180 --> 00:24:06,319 If I have an object, like this one, the one we are looking here, which one is the front view? 255 00:24:06,660 --> 00:24:14,220 Is this one? Is this one? Is this one? Is this one? We don't know. 256 00:24:14,900 --> 00:24:21,500 We need to agree. We need to decide, all of us together, if the exercise was drawing this object, 257 00:24:21,500 --> 00:24:25,500 we were supposed 258 00:24:25,500 --> 00:24:29,500 to decide, all of us, which one is the 259 00:24:29,500 --> 00:24:33,500 front view. Usually, or not usually, 260 00:24:33,500 --> 00:24:37,500 always, the moment we have decided which one is the front view, 261 00:24:37,500 --> 00:24:41,500 we will draw an arrow with the object. For instance, 262 00:24:41,500 --> 00:24:45,500 I will look for an example 263 00:24:45,500 --> 00:24:53,880 ... 264 00:24:53,880 --> 00:25:02,970 I have some exercises, but I don't want 265 00:25:02,970 --> 00:25:06,990 for example, yes, this one is fine. Imagine I have 266 00:25:06,990 --> 00:25:11,109 this cube. Can you see it? Which side of the cube 267 00:25:11,109 --> 00:25:14,589 is the front view? All of them are good enough 268 00:25:14,589 --> 00:25:19,049 so we need to decide which one is the front view. Front view in Spanish 269 00:25:19,049 --> 00:25:22,029 we say alza. So we usually 270 00:25:22,029 --> 00:25:26,630 with the view of the object, the one that 271 00:25:26,630 --> 00:25:30,269 when we draw an object using the perspective 272 00:25:30,269 --> 00:25:34,890 here in the first year of ESO we are not going to draw 273 00:25:34,890 --> 00:25:38,690 these types of representation. We are going to use just the 274 00:25:38,690 --> 00:25:42,849 three views of an object. But when we draw the object using the perspective 275 00:25:42,849 --> 00:25:46,630 we will also have to add an arrow pointing 276 00:25:46,630 --> 00:25:50,890 which one is the front view. So if this one is the front view 277 00:25:50,890 --> 00:25:54,230 we know that this one is the right side view 278 00:25:54,230 --> 00:25:57,069 we know that this one is the top view, ok? 279 00:25:58,890 --> 00:26:02,390 Could we draw the arrow here? Yes, why not? 280 00:26:02,750 --> 00:26:06,150 If we draw the arrow here, this one would be 281 00:26:06,150 --> 00:26:10,210 the front view, the side with the three, the side with 282 00:26:10,210 --> 00:26:14,109 one would be the left side view, and again this one would be 283 00:26:14,109 --> 00:26:17,710 the top view. Which one is better? Both of them are fine. 284 00:26:18,029 --> 00:26:21,470 Usually I prefer this one, the arrow here, because this way 285 00:26:21,470 --> 00:26:25,589 I'm sorry, we will be able to draw front, left side view 286 00:26:25,589 --> 00:26:29,109 and top view in a really easy way, ok 287 00:26:29,109 --> 00:26:32,670 so usually we need an arrow to complete the 288 00:26:32,670 --> 00:26:37,269 perspective drawing of the object, because this way we will decide which one is 289 00:26:37,269 --> 00:26:40,410 we will agree which one is the front view, ok 290 00:26:40,410 --> 00:26:47,029 questions, no questions 291 00:26:47,029 --> 00:26:57,940 there are no questions, ok, so let's move on a little bit 292 00:26:57,940 --> 00:27:01,940 with the theory. We already know the names 293 00:27:01,940 --> 00:27:06,119 of the three dimensions, height, length, and width. In Spanish, alto, largo, y ancho. 294 00:27:08,299 --> 00:27:09,559 Okay, you have to know them. 295 00:27:10,299 --> 00:27:13,980 It's part of the vocabulary of this unit. We also 296 00:27:13,980 --> 00:27:17,980 need, okay, dimension line and auxiliary line. 297 00:27:18,059 --> 00:27:21,980 We will study them later. Forget about them. You can't read 298 00:27:21,980 --> 00:27:25,059 them. You can't understand them. But later we will study. I prefer 299 00:27:25,059 --> 00:27:28,299 teach them using the context 300 00:27:28,299 --> 00:27:32,019 and their context. Now let's focus a little bit 301 00:27:32,019 --> 00:27:34,880 in these pieces of vocabulary. Sketches, diagrams 302 00:27:34,880 --> 00:27:36,900 and technical drawing. Sketch 303 00:27:36,900 --> 00:27:40,619 in Spanish we say boceto 304 00:27:40,619 --> 00:27:43,839 Sketch is hand drawing with just 305 00:27:43,839 --> 00:27:46,160 the fundamental ideas 306 00:27:46,160 --> 00:27:49,940 For example, if I 307 00:27:49,940 --> 00:27:52,920 want to draw 308 00:27:52,920 --> 00:28:02,039 this object. Imagine I want to draw this object. I can draw it this way using my sheet of paper 309 00:28:02,039 --> 00:28:19,359 and I will try to draw it the better I can. Something like that. I'm drawing it too fast 310 00:28:19,359 --> 00:28:26,640 take it into account. More or less it's the same object. More or less. I know I have drawn 311 00:28:26,640 --> 00:28:36,819 it too fast. I can do better with more time at anyway. This one would be a sketch bofeto 312 00:28:36,819 --> 00:28:43,819 of my object because it's hand-drawing with just the fundamental ideas, ok? 313 00:28:47,609 --> 00:28:53,730 This is the sketch of my object. This one and this one. This is the object, imagine 314 00:28:53,730 --> 00:28:59,369 this is the real one, imagine this is my sketch, ok? We also have the diagram. Again, it's 315 00:28:59,369 --> 00:29:06,369 a handwriting, but it has all the information needed, including measures. 316 00:29:06,369 --> 00:29:17,369 In some days, we will learn how to add measures using dimension lines and auxiliary lines. 317 00:29:17,369 --> 00:29:27,089 Using the sketch, I add the dimensions, for example, something like that. 318 00:29:27,089 --> 00:29:36,119 For instance, I don't know, 3. For instance, I don't know, 5. 319 00:29:36,119 --> 00:29:43,539 And I complete all the dimensions of the object. 320 00:29:43,539 --> 00:29:45,200 This one, for instance, three again. 321 00:29:45,779 --> 00:29:50,480 If I add all the lines of the object, I will have the diagram. 322 00:29:51,119 --> 00:29:52,160 Diagrama in Spanish. 323 00:29:52,559 --> 00:29:54,079 No es un boceto, es un diagrama. 324 00:29:54,079 --> 00:29:57,019 Because the diagram has more information than the sketch. 325 00:29:57,759 --> 00:30:03,779 And the technical drawing is a diagram, but instead of drawing it this way, 326 00:30:04,740 --> 00:30:11,460 I will draw it using a ruler and a compass or a computer. 327 00:30:11,460 --> 00:30:15,460 I can draw objects using the computer and this way I will 328 00:30:15,460 --> 00:30:19,319 have the exact picture of the object, the exact views of the object 329 00:30:19,319 --> 00:30:23,480 in a really precise way, ok? So remember 330 00:30:23,480 --> 00:30:27,519 these three pieces of vocabulary. Sketch, effecto, handwriting with no 331 00:30:27,519 --> 00:30:30,859 information, diagram, handwriting with the information 332 00:30:30,859 --> 00:30:35,539 technical drawing using a computer or a compass and a 333 00:30:35,539 --> 00:30:38,539 ruler and again with all the information, ok? 334 00:30:38,539 --> 00:30:42,319 So, these are 335 00:30:42,319 --> 00:30:44,819 the views of an object. 336 00:30:48,299 --> 00:30:55,720 Questions? No questions. 337 00:30:56,000 --> 00:30:59,759 I can read no. It means that there are no questions. 338 00:31:00,619 --> 00:31:01,579 Ok, let's move on. 339 00:31:07,599 --> 00:31:08,759 Let's do an exercise. 340 00:31:09,720 --> 00:31:13,559 You will do it later, but because we have time, we are going to do it now. 341 00:31:13,559 --> 00:31:17,440 I don't know where is it. I'm going to look for it. 342 00:31:24,539 --> 00:31:24,980 Here. 343 00:31:29,140 --> 00:31:30,779 I don't know where is it. 344 00:31:41,609 --> 00:31:42,789 Use other scales. 345 00:31:47,930 --> 00:31:51,519 Okay, this one. 346 00:31:52,000 --> 00:31:53,039 An interesting one. 347 00:31:54,119 --> 00:31:55,420 You will do it in the future. 348 00:31:55,819 --> 00:31:57,579 So, there are some problems 349 00:31:57,579 --> 00:31:59,720 because it's not... I have to improve it 350 00:31:59,720 --> 00:32:00,920 but anyway 351 00:32:00,920 --> 00:32:03,559 it was just a first approach 352 00:32:03,559 --> 00:32:05,420 to the exercise but I think it will work. 353 00:32:05,700 --> 00:32:07,660 Imagine we have this object. 354 00:32:08,319 --> 00:32:29,380 Okay. And imagine these are the six views of this object. We are going to place, we are going to click and drag and we are going to place them on their relative positions. Okay. This one will be our exercise. But you need something, you need to know something else. These dotted lines, what are they? 355 00:32:29,380 --> 00:32:33,380 Imagine the object was transparent. 356 00:32:33,380 --> 00:32:39,019 I'm going to explain it using this one. This one is not a good 357 00:32:39,019 --> 00:32:43,019 example. I want to look for something that is a better example. 358 00:32:43,019 --> 00:32:47,019 Yesterday, I mean on Monday, 359 00:32:47,019 --> 00:32:52,460 this one. This one is a good example. 360 00:32:52,460 --> 00:32:56,460 Here, we can draw continuous lines. 361 00:32:56,460 --> 00:33:00,460 But we can also draw dotted lines. Do you understand dotted lines? 362 00:33:00,460 --> 00:33:04,460 dotted line 363 00:33:04,460 --> 00:33:08,460 what does it mean, dotted line? 364 00:33:08,460 --> 00:33:16,839 Linea punteada, because dot in English 365 00:33:16,839 --> 00:33:20,839 means punto, dotted lines, linea punteada 366 00:33:20,839 --> 00:33:24,839 so if I go back to this one, I can draw 367 00:33:24,839 --> 00:33:28,839 continuous lines, but I can also draw dotted lines 368 00:33:28,839 --> 00:33:32,839 I think on Friday I draw 369 00:33:32,839 --> 00:33:36,839 the views of the object. I draw something like that. 370 00:33:36,839 --> 00:33:43,109 Front view. I will draw it in one minute. This is the front view. 371 00:33:43,109 --> 00:33:51,690 Front view is something like that. This one 372 00:33:51,690 --> 00:33:55,690 is this one. This one is this one. And this 373 00:33:55,690 --> 00:33:59,690 slope. Pendiente. Slope. 374 00:33:59,690 --> 00:34:05,059 Slope here. 375 00:34:05,059 --> 00:34:09,059 And this slope is this one. 376 00:34:09,059 --> 00:34:13,099 this, this one, this, this one, and I'm going to draw 377 00:34:13,099 --> 00:34:20,170 now the top view, remember that to draw the 378 00:34:20,170 --> 00:34:23,429 top view, we rotate from the top, this way 379 00:34:23,429 --> 00:34:26,389 the same way, the guy 380 00:34:26,389 --> 00:34:31,530 I think I have closed it, ok, anyway, remember 381 00:34:31,530 --> 00:34:34,909 how we rotate from the top 382 00:34:34,909 --> 00:34:39,570 from the front to the top, I rotate this way 383 00:34:39,570 --> 00:34:42,570 So, this is the front view. 384 00:34:42,570 --> 00:34:53,019 And now, the side view, interesting one. 385 00:34:53,019 --> 00:35:06,860 If I look at the object from this side, I will be able to see something like that. 386 00:35:06,860 --> 00:35:14,860 Do you agree that these are the three views of the object? 387 00:35:14,860 --> 00:35:17,860 Any question, any problem, any difficulty? 388 00:35:17,860 --> 00:35:20,860 No? Anyway, so I think you agree, no? 389 00:35:20,860 --> 00:35:23,860 I think that you agree that these are the three views of the object. 390 00:35:23,860 --> 00:35:27,280 But it's not complete. It's not complete because 391 00:35:27,280 --> 00:35:29,519 imagine the object was transparent. 392 00:35:30,619 --> 00:35:32,460 Imagine the object was transparent. 393 00:35:39,360 --> 00:35:43,000 In a previous version, the object, we could 394 00:35:43,000 --> 00:35:47,260 make it transparent. Now we couldn't. Now we cannot, I mean. 395 00:35:48,239 --> 00:35:50,639 But anyway, imagine the object was transparent. 396 00:35:50,880 --> 00:35:54,940 Imagine the object is here, but the object is transparent. Imagine it. 397 00:35:54,940 --> 00:35:58,239 what would be able if the object was transparent? 398 00:35:58,659 --> 00:36:02,719 we would be able to see that this slope is continuing 399 00:36:02,719 --> 00:36:05,800 can you imagine it? the slope is continuing 400 00:36:05,800 --> 00:36:10,119 if the object was transparent, we would be able to see 401 00:36:10,119 --> 00:36:13,539 the slope, can you imagine it? 402 00:36:14,980 --> 00:36:15,500 no? 403 00:36:17,719 --> 00:36:33,119 I want to draw the dotted line, maybe with the dotted line it would be easier 404 00:36:33,119 --> 00:36:37,119 this dotted line is representing 405 00:36:37,119 --> 00:36:41,119 that the slope, that this one 406 00:36:41,119 --> 00:36:45,119 can you see this one? the slope is continuing, continuing 407 00:36:45,119 --> 00:36:49,119 if the object was transparent, imagine this one 408 00:36:49,119 --> 00:36:53,119 is solid, we cannot see through it, but if the 409 00:36:53,119 --> 00:36:57,119 object was transparent, imagine the object was made of glass, can you imagine the object 410 00:36:57,119 --> 00:37:02,690 made of glass? I think you can, you don't understand 411 00:37:02,690 --> 00:37:06,389 Listen to me one second. Imagine the object is made of glass. 412 00:37:06,710 --> 00:37:09,550 Can you imagine the object made of glass? You can, of course. 413 00:37:10,170 --> 00:37:14,349 If this part of the object was made of glass, you will, obviously, 414 00:37:14,530 --> 00:37:18,070 you will be able to see this one, because there is nothing between your eyes and 415 00:37:18,070 --> 00:37:22,070 this slope. And here, if the object was made of glass, 416 00:37:22,289 --> 00:37:26,369 you will be able to see through it. You will be able to see that this 417 00:37:26,369 --> 00:37:30,909 slope is continuing. And because this 418 00:37:30,909 --> 00:37:34,909 object is made of glass, you will be able to see 419 00:37:34,909 --> 00:37:38,909 the slope, the continuing slope. 420 00:37:38,909 --> 00:37:42,909 To represent this one, to represent the idea that we will be able to see it 421 00:37:42,909 --> 00:37:46,909 if the object was transparent, we use the dotted line. 422 00:37:46,909 --> 00:37:55,929 Do you understand it now? 423 00:37:55,929 --> 00:38:06,429 You can open the 424 00:38:06,429 --> 00:38:10,429 microphone and you can speak in Spanish if you want. 425 00:38:10,429 --> 00:38:21,429 You mean that it is made of glass only in the part of the view? 426 00:38:21,429 --> 00:38:31,429 Of course, if the object is made of glass, you could see through, if the object was made of glass, even if it was only one part, I don't care, you could see what is behind, right? 427 00:38:31,429 --> 00:38:35,429 Yes, but if the object, everything or only what you see? 428 00:38:35,429 --> 00:38:41,190 what you need let's see if the object the object is never going to be totally you are thinking and 429 00:38:41,190 --> 00:38:44,489 if it is made of crystal everything is transparent with which I do not see anything it is like invisible 430 00:38:46,489 --> 00:38:51,750 well, imagine that it is not transparent at all that it is a little transparent and that here on the 431 00:38:51,750 --> 00:39:01,050 surfaces it is like a little dirty imagine it like that and then if I place the object that 432 00:39:01,050 --> 00:39:05,489 were totally glass with the surfaces a little dirty this part would not 433 00:39:05,489 --> 00:39:08,530 there would be no problem because you are always seeing it 434 00:39:08,530 --> 00:39:12,809 ok because there is nothing that prevents you from seeing it but if this was transparent with 435 00:39:12,809 --> 00:39:18,630 this part a little dirty you would not see through the object that there is something there 436 00:39:18,630 --> 00:39:25,530 and the way to represent in the drawing that I would see something there if the 437 00:39:25,530 --> 00:39:31,489 the object is transparent is using these discontinuous lines 438 00:39:31,489 --> 00:39:38,969 ok ok I understand now if the others 439 00:39:38,969 --> 00:39:42,969 formerly this exercise you could make the transparent object but they have 440 00:39:42,969 --> 00:39:46,849 removed that option is convinced that it followed but they have not removed it 441 00:39:46,849 --> 00:39:53,809 placed some new possibilities such as the profile change 442 00:39:53,809 --> 00:39:57,530 but but that they have deactivated it is a 443 00:39:57,530 --> 00:40:00,530 because it was very cool, it made that transparent object and you could see it. 444 00:40:04,530 --> 00:40:06,530 I don't know if around here... 445 00:40:06,530 --> 00:40:09,840 The others, do you understand it or not? 446 00:40:09,840 --> 00:40:11,840 I'll explain it another way. 447 00:40:11,840 --> 00:40:15,730 There were others around here that maybe... 448 00:40:15,730 --> 00:40:17,730 wait, maybe... 449 00:40:17,730 --> 00:40:22,260 they have removed it from here too. 450 00:40:22,260 --> 00:40:29,170 It implied that it became transparent, but that option has been removed. 451 00:40:29,170 --> 00:40:31,170 Questions? 452 00:40:31,170 --> 00:40:35,170 I understand, Lucas says yes. 453 00:40:35,170 --> 00:40:37,230 And the rest of you, I hope you are understanding. 454 00:40:38,769 --> 00:40:41,429 So now, let's do this exercise. 455 00:40:42,269 --> 00:40:43,690 Yes, yes, okay, I understand. 456 00:40:44,070 --> 00:40:51,090 Let's do this exercise, the one I was trying, this one. 457 00:40:51,750 --> 00:40:53,329 Imagine, we have this object. 458 00:40:54,550 --> 00:41:00,389 We have the six views, according to the way the cube can be unfold. 459 00:41:01,210 --> 00:41:01,889 Do you understand the idea? 460 00:41:01,889 --> 00:41:06,670 So, we are going to draw the different views. 461 00:41:06,670 --> 00:41:10,710 but we already have them. We have six views that are 462 00:41:10,710 --> 00:41:14,170 the front, the back, the left side view, the right side view, the top and the bottom. 463 00:41:14,929 --> 00:41:18,869 So, we will click and drag and place them 464 00:41:18,869 --> 00:41:20,630 in their correct positions, ok? 465 00:41:22,690 --> 00:41:28,699 I think 466 00:41:28,699 --> 00:41:35,460 we are going to do it together, ok? 467 00:41:38,139 --> 00:41:41,099 This is number one, this is two, this is three, 468 00:41:41,099 --> 00:41:43,139 4, 5 and 6, ok? 469 00:41:44,760 --> 00:41:48,619 so, think about it, I will give 5 minutes to you 470 00:41:48,619 --> 00:41:52,599 and think about where they have to be placed, remember 471 00:41:52,599 --> 00:41:56,980 right side view on the left, front view, left side view 472 00:41:56,980 --> 00:42:01,159 on the right, and this is the back view, bottom view 473 00:42:01,159 --> 00:42:04,380 on the top, and top view on the bottom, and you have 6 views 474 00:42:04,380 --> 00:42:09,320 1, 2, 3, 4, 5 and 6, 6 about 475 00:42:09,320 --> 00:42:12,099 six about where you have to place them. 476 00:42:13,420 --> 00:42:14,800 Five minutes to the exercise. 477 00:42:14,900 --> 00:42:15,820 Do you understand the exercise? 478 00:42:19,619 --> 00:42:23,679 Take a sheet of paper and think about it on a sheet of paper, okay? 479 00:42:32,320 --> 00:42:32,739 ¿Se entiende? 480 00:42:32,840 --> 00:42:33,360 Decidme algo. 481 00:42:42,159 --> 00:42:43,599 No decís nada, es que sí, vale. 482 00:42:43,739 --> 00:42:44,719 Me dice Ian que sí, vale. 483 00:42:44,800 --> 00:42:46,599 Pues entonces, os dejo aquí el objeto. 484 00:42:46,780 --> 00:42:47,380 Yes, yes, vale. 485 00:42:47,760 --> 00:42:48,920 Pues os dejo aquí el objeto. 486 00:42:50,179 --> 00:42:50,579 Este. 487 00:42:51,380 --> 00:42:52,980 Ah, y lo vais a hacer durante cinco minutos. 488 00:42:53,380 --> 00:42:54,079 Os doy cinco minutos. 489 00:43:23,739 --> 00:47:37,530 Are you finished? You have to imagine it's transparent. 490 00:47:37,530 --> 00:47:44,119 Okay, you have finished. Anyway, we will correct. If you have had 491 00:47:44,119 --> 00:47:48,119 any problem, don't worry. Pay attention to the correction and ask whatever you need 492 00:47:48,119 --> 00:47:52,119 to ask, okay? I repeat, I cannot read your minds. If you don't ask, 493 00:47:52,119 --> 00:47:56,119 it's not my fault, it's yours. So, anyway, let's correct it. 494 00:47:56,119 --> 00:48:00,119 Let me see, let me see... Here. For example, 495 00:48:00,119 --> 00:48:04,119 number one. Okay, anyway, I'm going to do it in a different way. 496 00:48:04,119 --> 00:48:09,119 Let's start with the front view. The front view is going to be drawn here. 497 00:48:09,119 --> 00:48:13,119 Do you agree? In the middle. Which one is the front view? What do you think? 498 00:48:13,119 --> 00:48:16,119 Number one, two, three, four, five and six. 499 00:48:16,119 --> 00:48:21,119 Three. Iyan says three. And the rest of you, what do you think? One, two or three? 500 00:48:21,119 --> 00:48:33,019 Two. 501 00:48:33,019 --> 00:48:36,019 Two? This one is the front view? 502 00:48:36,019 --> 00:48:43,019 Well, anyway, we have to decide which one is the front view. 503 00:48:43,019 --> 00:48:46,019 I didn't say anything and you didn't answer. 504 00:48:46,019 --> 00:48:52,019 Every time we find an object, we need to decide which one is the front view. 505 00:48:52,019 --> 00:48:56,019 I'm going to decide that this one is the front view, ok? 506 00:48:56,019 --> 00:49:02,019 So, if we decide that this one is the front view, the front view will be this one. 507 00:49:02,019 --> 00:49:04,019 Do you agree? It was my fault. 508 00:49:04,019 --> 00:49:08,019 default. Anyway, making mistakes is a good way to learn. 509 00:49:08,019 --> 00:49:12,019 And you didn't ask about the front view. As I said some minutes ago, 510 00:49:12,019 --> 00:49:16,019 we have to decide which one is the front view. We are going to decide that number 3 511 00:49:16,019 --> 00:49:20,019 is the front view, ok? If we look at the object from this 512 00:49:20,019 --> 00:49:24,019 position, we will see this one, this one, this one, 513 00:49:24,019 --> 00:49:28,019 this one, and the slope is this one, ok? This is the front view. 514 00:49:28,019 --> 00:49:32,019 Ok, the majority of you say 3, so 3 515 00:49:32,019 --> 00:49:38,179 all of you just javier navas has decided to anyway it's not a big problem javier don't worry 516 00:49:39,860 --> 00:49:44,739 imagine it's not a problem but this is you were free to decide we have decided that this is the 517 00:49:44,739 --> 00:49:51,619 front view okay now if this is the front view which one is the is the left side view number 518 00:49:51,619 --> 00:49:55,880 1, 2, 4, 5, or 6. What do you think? 519 00:49:56,519 --> 00:50:00,639 Left side view. 1, 2, 4, 5, or 6. 520 00:50:01,079 --> 00:50:03,880 2, 2, 2. Okay, 2, 2, 2. 521 00:50:04,059 --> 00:50:07,119 Okay, all of you think that is number 2. 522 00:50:07,579 --> 00:50:12,440 So, number 2, left side view has to be drawn here. 523 00:50:12,980 --> 00:50:14,119 Do you agree with the position? 524 00:50:15,420 --> 00:50:19,179 Left side view on the right. Okay, do you agree? 525 00:50:19,179 --> 00:50:21,179 no, Izan, what's the problem? 526 00:50:23,300 --> 00:50:26,380 Izan, the left side view is always drawn on the right 527 00:50:26,380 --> 00:50:30,820 everything is always on the position that looks 528 00:50:30,820 --> 00:50:34,639 the strange one, but this is the way 529 00:50:34,639 --> 00:50:38,320 this is because they have been projected to the cube and then we unfold the cube 530 00:50:38,320 --> 00:50:43,380 Izan, do you understand? You can open your microphone and you can talk if you want to 531 00:50:43,380 --> 00:50:50,849 ok, ok, we understand Izan, perfect 532 00:50:50,849 --> 00:51:02,659 I'm okay and now I understand okay and let's go back what about the top view which one is the top 533 00:51:02,659 --> 00:51:15,760 view one four five or six this one needs a line here one four five or six which one is the top 534 00:51:15,760 --> 00:51:23,219 view six six okay you all of you you agree that the top view is number six so we click and drag 535 00:51:23,219 --> 00:51:27,579 Where do I have to click it? To drag it? Here or here? 536 00:51:28,300 --> 00:51:31,139 It's the top view. Where do I have to drag it? 537 00:51:31,380 --> 00:51:34,639 On the bottom or on the top? Down. 538 00:51:35,800 --> 00:51:38,440 Jorge Jimenez says down. And the rest of you, what do you think? 539 00:51:39,760 --> 00:51:43,340 Up or down? It's the top view. Where do I drag it? 540 00:51:43,340 --> 00:51:46,239 Down. Okay, down. You are right. 541 00:51:46,900 --> 00:51:51,440 I have to drag it on the bottom. Because everything 542 00:51:51,440 --> 00:51:57,679 has to be in the opposite position. The one that seems the opposite one. Now, I'm going 543 00:51:57,679 --> 00:52:05,820 to draw the, this one has to be the, because it's on the left, it's going to be the right 544 00:52:05,820 --> 00:52:13,679 side view. Which one is the right side view? 1, 4 or 5? What do you think? 1, 1, 1, ok. 545 00:52:13,679 --> 00:52:20,679 All of you that the right side view is the, is number 1. Number 1 is going to be here. 546 00:52:20,679 --> 00:52:26,679 Here, there are dotted lines, because we can imagine that if we are looking at the object from this position, 547 00:52:26,679 --> 00:52:31,679 we will be able to see a cube. But if the object was transparent, 548 00:52:31,679 --> 00:52:36,679 we would be able to see this one, that is this one, and we would be able 549 00:52:36,679 --> 00:52:41,679 to see the slope, that is this one. Can you see it? I think it's easy. 550 00:52:41,679 --> 00:52:46,679 Okay? Any problem? Any question? No? Okay. 551 00:52:46,679 --> 00:52:50,559 Let's finish the exercise. What happens with the back view? 552 00:52:50,639 --> 00:52:54,139 The back view is the one that is here. Number 4 553 00:52:54,139 --> 00:53:01,210 or number 5? 5. 554 00:53:03,690 --> 00:53:12,920 This one is the back view. 5, 5, 5, 4. Victoria says 4. 555 00:53:14,199 --> 00:53:15,159 And Victoria is right. 556 00:53:16,219 --> 00:53:21,119 The back view is number 4. That's how I look at it. 557 00:53:21,920 --> 00:53:24,380 Looking at the back view sometimes is difficult because 558 00:53:24,380 --> 00:53:28,380 because usually we are not used to it. 559 00:53:28,380 --> 00:53:32,380 This is the back view. If we were looking at the object from 560 00:53:32,380 --> 00:53:36,380 behind, we would see a cube. 561 00:53:36,380 --> 00:53:40,380 But if the object was transparent, we would see 562 00:53:40,380 --> 00:53:44,380 this one, this one, and this one. 563 00:53:44,380 --> 00:53:48,380 We would see three pieces of surfaces. 564 00:53:48,380 --> 00:53:52,380 This one was this one, this one 565 00:53:52,380 --> 00:53:56,380 was this one and this one was this one. 566 00:53:56,380 --> 00:54:00,380 So we have three pieces of surfaces so this is the back 567 00:54:00,380 --> 00:54:04,380 view. And the last one is obviously 568 00:54:04,380 --> 00:54:08,380 the bottom view and it's going to be tracked here 569 00:54:08,380 --> 00:54:12,380 on the top. And imagine yourselves looking at the object from above 570 00:54:12,380 --> 00:54:16,380 you would be able to see a kind of a square 571 00:54:16,380 --> 00:54:20,380 but if the object was transparent you would be able 572 00:54:20,380 --> 00:54:23,579 to see this L that is this one 573 00:54:23,579 --> 00:54:27,900 and the slope that is this one. So these are 574 00:54:27,900 --> 00:54:32,179 the six views of the object places on 575 00:54:32,179 --> 00:54:35,920 their correct positions and using the dotted lines. 576 00:54:35,920 --> 00:54:43,760 I was referring to the four. 577 00:54:44,659 --> 00:54:47,519 Anyway, don't worry. We are just learning. 578 00:54:48,500 --> 00:54:52,000 About the dotted lines, you need to know the meaning of them. 579 00:54:52,000 --> 00:54:55,280 if we do exercises in the class 580 00:54:55,280 --> 00:54:58,119 or using the virtual classroom 581 00:54:58,119 --> 00:55:01,440 I'm not going to ask you to draw dotted lines 582 00:55:01,440 --> 00:55:02,780 because sometimes it's difficult 583 00:55:02,780 --> 00:55:06,679 but you have to understand the meaning of them 584 00:55:06,679 --> 00:55:08,679 and you have to recognize them 585 00:55:08,679 --> 00:55:12,579 if you find an object with them 586 00:55:12,579 --> 00:55:16,599 so we have finished 587 00:55:16,599 --> 00:55:19,360 with the theory and with the exercises today 588 00:55:19,360 --> 00:55:21,780 any questions before we leave? 589 00:55:22,000 --> 00:55:40,050 Something you want to ask? Anything you want to ask? Nothing? Nothing to ask? No? Yes, Iyan, you have to make a unit now. 590 00:55:40,050 --> 00:55:49,750 What do you mean to make a unit? You can open the microphone if you want to, you can speak in Spanish if you want to. 591 00:55:49,750 --> 00:55:55,750 We have to make a new unit for this? 592 00:55:55,750 --> 00:55:58,750 We are in a new unit, yes. 593 00:55:58,750 --> 00:56:00,750 Okay. 594 00:56:00,750 --> 00:56:03,750 Who else wanted to ask? 595 00:56:03,750 --> 00:56:09,750 Yes, because why is it in the opposite position? 596 00:56:09,750 --> 00:56:12,750 Why are they in the opposite position? 597 00:56:12,750 --> 00:56:14,750 Yes. 598 00:56:14,750 --> 00:56:18,389 I'm sharing the screen with you, I think. 599 00:56:18,869 --> 00:56:20,849 Do you remember the video we watched before? 600 00:56:22,150 --> 00:56:24,010 Where is it? I'm going to open it again. 601 00:56:30,719 --> 00:56:33,139 Guillain, did you ask about this before or was it someone else? 602 00:56:37,559 --> 00:56:38,800 It wasn't me. 603 00:56:39,280 --> 00:56:43,500 It was you. It wasn't you. 604 00:56:44,880 --> 00:56:46,239 The idea is, look. 605 00:56:46,239 --> 00:56:48,440 I'll explain it in Spanish. 606 00:56:50,539 --> 00:56:52,139 This is the front view. 607 00:56:53,099 --> 00:56:54,260 The raised, we say in Spanish. 608 00:56:55,019 --> 00:56:55,760 The yellows. 609 00:56:56,639 --> 00:56:57,440 Do you agree with me? 610 00:56:59,079 --> 00:56:59,559 Yes. 611 00:57:00,280 --> 00:57:01,380 Where have we drawn them? 612 00:57:01,599 --> 00:57:01,920 Behind. 613 00:57:01,920 --> 00:57:04,900 It's like if we saw it and pushed it back. 614 00:57:05,679 --> 00:57:07,320 What happens with the left side view? 615 00:57:07,500 --> 00:57:08,659 The profile, we say in Spanish. 616 00:57:08,719 --> 00:57:09,079 The green. 617 00:57:09,539 --> 00:57:12,880 We're seeing it from the left, but we push it to the right. 618 00:57:13,019 --> 00:57:13,440 Here. 619 00:57:14,380 --> 00:57:15,800 And what happens with the top view? 620 00:57:15,800 --> 00:57:21,679 which is the blue one, we see it from above but we push it down 621 00:57:21,679 --> 00:57:30,079 so once I have the three, the six, it could be six perfectly 622 00:57:30,079 --> 00:57:36,179 and I remove the object, the next step is to unfold the cube 623 00:57:36,179 --> 00:57:38,179 We have to select the two. 624 00:57:38,179 --> 00:57:40,179 We have to select the two. 625 00:57:40,179 --> 00:57:42,179 It's a bit... 626 00:57:42,179 --> 00:57:44,179 It's a bit... 627 00:57:44,179 --> 00:57:46,179 That's why the top view is down here 628 00:57:46,179 --> 00:57:48,179 and that's why the left side view is on the right. 629 00:57:48,179 --> 00:57:51,550 Okay, where is it? 630 00:57:51,550 --> 00:57:53,550 That's why everything is apparently 631 00:57:53,550 --> 00:57:55,550 in the wrong position, 632 00:57:55,550 --> 00:57:57,550 which is not wrong. 633 00:57:57,550 --> 00:57:59,550 It's all the other way around, 634 00:57:59,550 --> 00:58:01,550 and it's because it's projected on a cube 635 00:58:01,550 --> 00:58:03,550 and when it's projected on a cube 636 00:58:03,550 --> 00:58:05,550 it's on the opposite side of what 637 00:58:05,550 --> 00:58:30,409 more questions no more questions if there are no questions no okay so we are going to leave 638 00:58:30,409 --> 00:58:37,329 there are no more no more questions okay you can leave the classroom the virtual classroom you want 639 00:58:49,980 --> 00:58:55,980 Thank you.
