00:00:01,580 --> 00:00:18,359
Good. Hello. Well, I think it's important to remember that we are studying a way to express our ideas.

2
00:00:18,359 --> 00:00:28,179
So it isn't mathematics, it isn't computational thinking, but obviously we

3
00:00:28,179 --> 00:00:37,479
can use different methods to ease our learning. So in this case, in this

4
00:00:37,479 --> 00:00:48,159
particular case, what we want to do is represent objects, 3D objects, in just

5
00:00:48,159 --> 00:01:00,399
two dimensions that is our sheet of paper this is a very difficult thing if you if you think

6
00:01:00,399 --> 00:01:13,439
in this slowly and carefully you are using one dimension so it's not easy to do and if you want

7
00:01:13,439 --> 00:01:26,540
that everybody can understand what you are expressing is, if it is possible, more difficult.

8
00:01:26,540 --> 00:01:32,019
So trying to think how we can do it.

9
00:01:32,019 --> 00:01:36,200
We usually do it in a very intuitive way.

10
00:01:36,200 --> 00:01:46,959
Children draw so many things and the things they are representing are 3D objects.

11
00:01:46,959 --> 00:02:00,299
So in any case they use perspective, but obviously not a rule for the perspective.

12
00:02:00,299 --> 00:02:08,740
So what usually happens is that other person can understand what you are really representing

13
00:02:08,740 --> 00:02:13,419
and what you are really saying.

14
00:02:13,419 --> 00:02:29,099
So we have to use, we need to use the rules in order to be understood by other people.

15
00:02:29,099 --> 00:02:40,780
And with this thing, we can distinguish three different kinds of perspectives, which are

16
00:02:40,780 --> 00:02:45,020
Diedrich perspective, Isometric perspective and Gavarier.

17
00:02:45,020 --> 00:02:56,620
And in this video, we are going to explain the easiest one, which is Diedrich perspective.

18
00:02:56,620 --> 00:03:06,340
into consideration some rules so we are going to express our object in European system which

19
00:03:06,340 --> 00:03:21,039
is a particular way or a particular the edit perspective so let's let's begin well if you

20
00:03:21,039 --> 00:03:35,979
if you put your object into a box or something with a cube or so similar, you can project the

21
00:03:35,979 --> 00:03:47,939
object to the faces of the cube or the box in which there is your object. So the effect is

22
00:03:47,939 --> 00:03:56,770
like using a lamp to illuminate a figure in three dimensions. Each of these

23
00:03:56,770 --> 00:04:04,629
projected drawings is called an orthogonal projection or view.

24
00:04:04,629 --> 00:04:22,329
and if the box one box will have six faces so there are six views if you located the the views

25
00:04:22,329 --> 00:04:36,980
in this way as you can see in this in this slide you are using European system so it's very easy

26
00:04:36,980 --> 00:04:47,959
because there always a view which is most the most representative of the object it's like a

27
00:04:47,959 --> 00:04:55,879
title such a title and this view is usually called front elevation it is the

28
00:04:55,879 --> 00:05:01,819
main primary view it is always the most representative face of the object we

29
00:05:01,819 --> 00:05:09,560
can indicate it with an arrow because obviously is something subjective it

30
00:05:09,560 --> 00:05:18,579
depends person we are who are looking to the the object not it's not something

31
00:05:18,579 --> 00:05:35,060
well it's a common sense obviously but it depends a person so we usually

32
00:05:35,060 --> 00:05:42,839
indicate the front elevation using an arrow if you have the front elevation

33
00:05:42,839 --> 00:05:55,480
just behind front elevation you should draw the plan obviously the not the

34
00:05:55,480 --> 00:06:06,160
bottom plan but the upper plan. You also have left and right elevation which

35
00:06:06,160 --> 00:06:17,199
adds as you can imagine the orthogonal progression on the left and on the right.

36
00:06:17,199 --> 00:06:28,480
and finally you have also can have the rear elevation all the objects can be represented

37
00:06:28,480 --> 00:06:41,439
just only with three views you don't need more because the views are usually similar and the

38
00:06:41,439 --> 00:06:47,279
differences are just lines type of line which is continuous or discontinuous line

39
00:06:47,279 --> 00:06:56,100
so you don't need more than three views for each object but the problem is how

40
00:06:56,100 --> 00:07:03,060
can how you can get these views because it's not simple and there isn't

41
00:07:03,060 --> 00:07:10,860
any recipe and any algorithm to do that I can give you some advices to do

42
00:07:10,860 --> 00:07:18,480
and I think they are good advices obviously but the best way if you want to learn is training

43
00:07:18,480 --> 00:07:25,839
and training and training a lot and do and and draw and draw and write out because it's the

44
00:07:25,839 --> 00:07:37,259
only way and somebody that there is a people who who usually say that colors can help you

45
00:07:37,259 --> 00:07:44,660
to to know the view but believe me because this is true the only way is

46
00:07:44,660 --> 00:07:54,199
training and training and training a good advice is thinking the object

47
00:07:54,199 --> 00:08:04,980
inside a box and obviously the views of the boxes are always rectangles and are

48
00:08:04,980 --> 00:08:14,759
very very very simple views so if you can do this the views of the rectangles

49
00:08:14,759 --> 00:08:23,699
are very simple to see and transforming the rectangles in the in the figures

50
00:08:23,699 --> 00:08:33,659
taking in consideration what is what what what you have to pick off or you

51
00:08:33,659 --> 00:08:44,580
have to put on a to get your your object it could be a way it may be a way to get

52
00:08:44,580 --> 00:08:55,559
your job use it could be and another would advise what is this example the

53
00:08:55,559 --> 00:09:01,679
the retangles are very very similar to this figure so it very very easy to

54
00:09:01,679 --> 00:09:11,240
transform the rectangles into the views of this feature. Here in the front elevation there is a

55
00:09:11,240 --> 00:09:26,639
hole and in the others view there is a line so it's very very simple but what usually happens

56
00:09:26,639 --> 00:09:36,720
is that the figures are complex and in this particular case the rectangles are

57
00:09:36,720 --> 00:09:45,919
not so easy to use. A good advice could be to discompose your object into

58
00:09:45,919 --> 00:09:54,679
simple geometric figures, for example, cubes, for example, cylinders,

59
00:09:54,679 --> 00:10:06,620
for example spheres or so on and it's also important to know which is a hole or an object

60
00:10:06,620 --> 00:10:23,860
so getting the views of each part and then compose and join each part in the single view

61
00:10:23,860 --> 00:10:33,179
it can be important and it can be a good way to get the views in complex objects

62
00:10:33,179 --> 00:10:47,399
but although it could be very repetitive the best way is training and training a

63
00:10:47,399 --> 00:10:56,639
lot to get views of different objects that that's just only a few examples so in the blog you you

64
00:10:56,639 --> 00:11:10,259
can have a lot of examples to do and is the best way believe me so I see you in the next video
