1 00:00:00,000 --> 00:00:18,500 Hello everyone! This is Alicja. Welcome to my home art studio. Our starring guest today is... 2 00:00:18,500 --> 00:00:21,500 Hello fellow artists! 3 00:00:21,500 --> 00:00:30,500 ...Matsula Bosbok. And today we will be learning about technical drawing tools and how to use them. 4 00:00:30,500 --> 00:00:36,140 Now, technical drawing is a very precise way of drawing. 5 00:00:36,140 --> 00:00:39,740 It is used to draw plans, instructions. 6 00:00:39,740 --> 00:00:46,140 It is standardized, which means it follows certain established rules. 7 00:00:46,140 --> 00:00:50,140 To do it, we need some special tools like this. 8 00:00:50,140 --> 00:00:52,780 A hard graphic pencil. 9 00:00:52,780 --> 00:00:56,899 These pencils are labeled with an H and a number. 10 00:00:56,899 --> 00:01:00,859 They draw lighter and are easier to erase. 11 00:01:00,859 --> 00:01:05,560 The higher the number, the harder the pencil. 12 00:01:05,560 --> 00:01:07,340 A bow compass. 13 00:01:07,340 --> 00:01:11,680 This tool is used for drawing arcs and circles. 14 00:01:11,680 --> 00:01:13,780 If you don't have one of your own, 15 00:01:13,780 --> 00:01:42,980 you can make a paper one, like this. 16 00:01:42,980 --> 00:01:45,280 Graduated ruler. 17 00:01:45,280 --> 00:01:47,739 This is used to measure distances 18 00:01:47,739 --> 00:01:50,920 and draw straight lines. 19 00:01:50,920 --> 00:01:58,879 Triangular set squares. These two triangles work together. This is the 45 degree set square, 20 00:01:59,379 --> 00:02:07,480 que es cuadra, and this is the 60 degree set square, cartabón. They are both right angle 21 00:02:07,480 --> 00:02:18,159 triangles, which means they have a 90 degree angle here and here. Besides, this one has 22 00:02:18,159 --> 00:02:31,199 to 45 degree angles here and here and this one has one 60 degree angle and one 30 degree angle 23 00:02:32,560 --> 00:02:38,719 if you need it i recommend you write down the degrees of each angle so you can remember them 24 00:02:39,759 --> 00:02:43,360 if you don't have these at home you can make some paper ones 25 00:02:43,360 --> 00:02:53,360 The protractor. This tool is used to measure, transfer and draw angles. 26 00:02:53,360 --> 00:02:59,360 And of course we will be still using a rubber to fix mistakes and a pencil sharpener. 27 00:02:59,360 --> 00:03:02,360 But how do we use the tools? 28 00:03:02,360 --> 00:03:06,360 Good question, Spock. Let's see. 29 00:03:06,360 --> 00:03:17,360 The bow carcass. The point should be a bit longer than the graphite lead. If it isn't, adjust it, like this. 30 00:03:17,360 --> 00:03:29,740 Put the point where the centre of the circle is going to be, vertical, and press gently but firmly. The paper doesn't feel pink. 31 00:03:29,740 --> 00:03:36,680 If you need it, put some book or more paper underneath. 32 00:03:36,680 --> 00:03:41,240 Adjust the measure of the bow compass with both hands. 33 00:03:41,240 --> 00:03:47,379 To draw the circle, hold the tip between your index finger and thumb, trying to turn it 34 00:03:47,379 --> 00:03:49,919 as gently as possible. 35 00:03:49,919 --> 00:03:55,879 Think of a ballerina dancing. 36 00:03:55,879 --> 00:03:57,699 The set squares. 37 00:03:57,699 --> 00:04:04,000 set squares can be used to draw angles using them as templates with the 45 38 00:04:04,000 --> 00:04:15,439 degree set square we can draw 45 degrees 90 degrees and 135 degrees with the 60 39 00:04:15,439 --> 00:04:26,319 degrees set square we can draw 30 degrees 60 degrees 90 degrees 120 40 00:04:26,319 --> 00:04:45,220 degrees and 150 degrees if we combine them we can draw 15 degrees 75 degrees 105 degrees and 165 41 00:04:45,220 --> 00:04:54,629 degrees these triangles can also be used to draw parallel and perpendicular lines parallel lines 42 00:04:54,629 --> 00:05:00,209 are straight lines that never meet and always skip the same distance between 43 00:05:00,209 --> 00:05:06,449 them. Perpendicular lines are straight lines that cross one another creating 44 00:05:06,449 --> 00:05:14,550 four 90-degree angles. To draw parallel lines, place a 45-set-square 45 00:05:14,550 --> 00:05:21,509 longest side, the hypotenuse, just over the first line. Then place a 60-degree 46 00:05:21,509 --> 00:05:30,149 set square hypotenuse beside and hold it very firm. Now you can slide the 45 degree set square 47 00:05:30,709 --> 00:05:37,430 and draw as many parallel lines as you want. This also works with the triangles in different 48 00:05:37,430 --> 00:05:44,230 positions or with a triangle and a ruler as long as you can slide one of them. 49 00:05:44,230 --> 00:05:55,230 To draw the vernacular lines, place the 45° Z-square just as before, and then the 60° Z-square. 50 00:05:55,230 --> 00:06:08,230 Now this is the tough part. Rotate the 45° Z-square so that it looks like this, like an arrow pointing to the 60° Z-square. 51 00:06:08,230 --> 00:06:16,790 square now the hypotenuse the longest side of the 45 degree set square is perpendicular to the first 52 00:06:16,790 --> 00:06:25,189 line and we can slide it to draw as many perpendicular lines as we want it doesn't 53 00:06:25,189 --> 00:06:30,629 matter the position of the lines you are always going to rotate the rollers like this 54 00:06:30,629 --> 00:06:37,629 The protractor. Let's use the protractor for measuring an angle. 55 00:06:37,629 --> 00:06:44,629 Your protractor will have a little point or T or hole in this spot. 56 00:06:44,629 --> 00:06:48,629 Place that over the vertex of the angle. 57 00:06:48,629 --> 00:06:55,629 Now, depending on where is the angle growing to, we will measure clockwise to the right 58 00:06:55,629 --> 00:07:17,810 or counterclockwise to the left. 59 00:07:17,810 --> 00:07:25,009 this angle is growing to the right so i'm going to measure it clockwise in this case 60 00:07:25,009 --> 00:07:30,769 my angle is growing to the left so i'm going to measure it counterclockwise 61 00:07:33,649 --> 00:08:02,980 i place my point over the vertex there i place my point over the vertex 62 00:08:02,980 --> 00:08:12,339 There! It's your turn! 63 00:08:12,339 --> 00:08:17,339 Fascinating! What are we going to do now? 64 00:08:17,339 --> 00:08:24,339 We are making a flower with a bow compass and a composition with parallel and perpendicular lines. 65 00:08:24,339 --> 00:11:03,399 And that is all for today! 66 00:11:03,399 --> 00:11:06,399 Well, that was quite fun! 67 00:11:06,399 --> 00:11:14,440 Well, thank you Spock. I hope you had fun too and I will see you again soon. Take care and bye-bye.
