Good. Hello. Well, I think it's important to remember that we are studying a way to express our ideas. 00:00:01
So it isn't mathematics, it isn't computational thinking, but obviously we 00:00:18
can use different methods to ease our learning. So in this case, in this 00:00:28
particular case, what we want to do is represent objects, 3D objects, in just 00:00:37
two dimensions that is our sheet of paper this is a very difficult thing if you if you think 00:00:48
in this slowly and carefully you are using one dimension so it's not easy to do and if you want 00:01:00
that everybody can understand what you are expressing is, if it is possible, more difficult. 00:01:13
So trying to think how we can do it. 00:01:26
We usually do it in a very intuitive way. 00:01:32
Children draw so many things and the things they are representing are 3D objects. 00:01:36
So in any case they use perspective, but obviously not a rule for the perspective. 00:01:46
So what usually happens is that other person can understand what you are really representing 00:02:00
and what you are really saying. 00:02:08
So we have to use, we need to use the rules in order to be understood by other people. 00:02:13
And with this thing, we can distinguish three different kinds of perspectives, which are 00:02:29
Diedrich perspective, Isometric perspective and Gavarier. 00:02:40
And in this video, we are going to explain the easiest one, which is Diedrich perspective. 00:02:45
into consideration some rules so we are going to express our object in European system which 00:02:56
is a particular way or a particular the edit perspective so let's let's begin well if you 00:03:06
if you put your object into a box or something with a cube or so similar, you can project the 00:03:21
object to the faces of the cube or the box in which there is your object. So the effect is 00:03:35
like using a lamp to illuminate a figure in three dimensions. Each of these 00:03:47
projected drawings is called an orthogonal projection or view. 00:03:56
and if the box one box will have six faces so there are six views if you located the the views 00:04:04
in this way as you can see in this in this slide you are using European system so it's very easy 00:04:22
because there always a view which is most the most representative of the object it's like a 00:04:36
title such a title and this view is usually called front elevation it is the 00:04:47
main primary view it is always the most representative face of the object we 00:04:55
can indicate it with an arrow because obviously is something subjective it 00:05:01
depends person we are who are looking to the the object not it's not something 00:05:09
well it's a common sense obviously but it depends a person so we usually 00:05:18
indicate the front elevation using an arrow if you have the front elevation 00:05:35
just behind front elevation you should draw the plan obviously the not the 00:05:42
bottom plan but the upper plan. You also have left and right elevation which 00:05:55
adds as you can imagine the orthogonal progression on the left and on the right. 00:06:06
and finally you have also can have the rear elevation all the objects can be represented 00:06:17
just only with three views you don't need more because the views are usually similar and the 00:06:28
differences are just lines type of line which is continuous or discontinuous line 00:06:41
so you don't need more than three views for each object but the problem is how 00:06:47
can how you can get these views because it's not simple and there isn't 00:06:56
any recipe and any algorithm to do that I can give you some advices to do 00:07:03
and I think they are good advices obviously but the best way if you want to learn is training 00:07:10
and training and training a lot and do and and draw and draw and write out because it's the 00:07:18
only way and somebody that there is a people who who usually say that colors can help you 00:07:25
to to know the view but believe me because this is true the only way is 00:07:37
training and training and training a good advice is thinking the object 00:07:44
inside a box and obviously the views of the boxes are always rectangles and are 00:07:54
very very very simple views so if you can do this the views of the rectangles 00:08:04
are very simple to see and transforming the rectangles in the in the figures 00:08:14
taking in consideration what is what what what you have to pick off or you 00:08:23
have to put on a to get your your object it could be a way it may be a way to get 00:08:33
your job use it could be and another would advise what is this example the 00:08:44
the retangles are very very similar to this figure so it very very easy to 00:08:55
transform the rectangles into the views of this feature. Here in the front elevation there is a 00:09:01
hole and in the others view there is a line so it's very very simple but what usually happens 00:09:11
is that the figures are complex and in this particular case the rectangles are 00:09:26
not so easy to use. A good advice could be to discompose your object into 00:09:36
simple geometric figures, for example, cubes, for example, cylinders, 00:09:45
for example spheres or so on and it's also important to know which is a hole or an object 00:09:54
so getting the views of each part and then compose and join each part in the single view 00:10:06
it can be important and it can be a good way to get the views in complex objects 00:10:23
but although it could be very repetitive the best way is training and training a 00:10:33
lot to get views of different objects that that's just only a few examples so in the blog you you 00:10:47
can have a lot of examples to do and is the best way believe me so I see you in the next video 00:10:56
