00:00:00,370 --> 00:00:13,869
As you know, we are living in what usually people call information age society, so it's important for us to use computers for everything and to know how to do it.

2
00:00:13,869 --> 00:00:38,710
Drawing is also important. When we use the computer to do our draw, our design, we have the opportunity of transferring these files into files that a 3D printer can understand, so it can print the objects in 3D dimensions.

3
00:00:38,710 --> 00:00:48,710
Well, this course is very basic, so we are just only introduced to do that.

4
00:00:48,710 --> 00:00:56,710
To reach this target, we are going to use a program which is called SketchUp.

5
00:00:56,710 --> 00:01:05,709
SketchUp is very simple to use, as you can see, in a basic way.

6
00:01:05,709 --> 00:01:14,980
So the first thing that we must do is choose a template. I recommend you the template in millimeters.

7
00:01:14,980 --> 00:01:19,980
The templates are different and they are classified depending on the measures.

8
00:01:19,980 --> 00:01:37,319
When you open your SketchUp, the first thing that you usually see is this woman.

9
00:01:37,319 --> 00:01:42,319
So you must select it and delete it because you need this area.

10
00:01:42,319 --> 00:01:57,159
So, well, you have the name bar and some functions that you also have using icons, so you can

11
00:01:57,159 --> 00:02:01,000
use the icons or you can use what you want.

12
00:02:01,000 --> 00:02:11,639
So the first thing that we are going to do is explain the tools that let you move into

13
00:02:11,639 --> 00:02:22,360
this 3D space. We have this one, which is the pan, and with the pan you can move the

14
00:02:22,360 --> 00:02:31,219
3D axis of the space, you can move. This is the other, that is orbit, that it also let

15
00:02:31,219 --> 00:02:41,120
you move, rotation. And other important one is the thumb, that let you to do the

16
00:02:41,120 --> 00:02:53,000
the objects bigger or smaller using the tool. To draw you have here lines, arcs, shapes,

17
00:02:53,000 --> 00:03:03,389
you can also have in draw obviously because they are tools to draw. Here you have lines,

18
00:03:03,389 --> 00:03:17,069
are shapes we are going to start with a rectangle so if you see at the bottom on the left hand

19
00:03:17,069 --> 00:03:32,949
corner you can see the measure so we are going to draw a rectangle that you can change your measures

20
00:03:33,389 --> 00:03:41,449
With mouse you can also change the shapes.

21
00:03:41,449 --> 00:03:52,490
Well, it's a rectangle, it's a square, I'm going to do a rectangle, a better rectangle.

22
00:03:52,490 --> 00:04:02,770
So, we can draw, obviously, it's supervised.

23
00:04:02,770 --> 00:04:11,770
With tools you can select, you can erase or delete something, move it, rotate, change the scale.

24
00:04:11,770 --> 00:04:31,509
But all of these are important dimensions, for example, which are important also because you can know the dimension of this object.

25
00:04:31,509 --> 00:04:44,810
But we are going to choose this one, which is push and pull.

26
00:04:44,810 --> 00:05:09,629
So if I select the surface and then this tool, I can convert the surface into a volume, and this is the way.

27
00:05:09,629 --> 00:05:42,120
You can also do holes if you want, but we can do different things, we can do other more complicated things.

28
00:05:42,120 --> 00:06:29,319
For example, I can also use lines, and with lines I can do different kinds of figures.

29
00:06:29,319 --> 00:06:35,920
So now we have another surface, which is a triangle.

30
00:06:35,920 --> 00:06:44,709
And now, if I use this one, I have a very complex figure, a very complex object.

31
00:06:44,709 --> 00:07:03,360
We also, for example, can select this line and delete it, or select the other line.

32
00:07:03,360 --> 00:07:07,759
We also can paint it and do different things.

33
00:07:07,759 --> 00:07:21,319
And obviously you can save, that is the last part, and also export to 3D model that can

34
00:07:21,319 --> 00:07:29,540
transfer in a file that a 3D printer can understand, or to the graphic, for

35
00:07:29,540 --> 00:07:46,319
example, any format or so on. Well, this is all for today. I hope you can find this

36
00:07:46,319 --> 00:07:49,680
useful for you.
