Well, this tutorial is to explain how to use OpenSCAD. 00:00:00
OpenSCAD is an open source software that you can download the zip format from your virtual 00:00:09
classroom. 00:00:25
You must unzip and click inside, and inside you can see the program which you can accept. 00:00:26
It's not necessary if you don't want to set up in your computer. 00:00:37
Well, firstly, the most interesting thing of this program is the same model as you have in QCAT, but in QCAT you have two-dimension figures and in OpenSCAD you have three-dimension figures. 00:00:51
So, in this area you can know the result, and here you can tell the commands. 00:01:24
Well, there are three main figures that can change using different parameters. 00:01:31
The easiest one is cube. 00:01:41
You have three parameters, weight, length, and height, so you must type the value of 00:01:43
parameters using the keyboard, at the end type semicolon and finally press F5 00:02:03
and this is the result, this is the cube. If you want to create a cylinder you 00:02:23
must type cylinder and then you have three parameters which are height for example 00:02:34
and the radio of the two bases then then semicolon and at the end a five 00:02:49
With cylinder you can also have horizontal cone, if you type one of the bases O, you 00:03:00
have a cone. 00:03:12
And finally you have spheres, you can have spheres, spheres just only have one parameter, 00:03:15
which is the radio, that is the result. 00:03:29
But as you can see, indeed, the sphere has so many faces. 00:03:34
You can change the number of faces using $ and this is the result. 00:03:42
You can also use this command if you want to create pyramids, for example. 00:03:54
If you see a cylinder, you can create pyramid and prismas, for example, we're going to do 00:04:00
10. 00:04:22
10. 00:04:23
If you do it in this way, you have a cylinder. 00:04:24
you added this parameter you have another figure and if you change this 00:04:32
other parameter you have pyramid of different faces but apart from this you 00:04:59
You can also move the different figures. 00:05:12
You see two possibilities that are Translate, Translation and Rotation. 00:05:16
We come back to our cube. 00:05:25
We have cube, we have a cube of 20, 20, 20 and this is the result. 00:05:27
If you want to translate the cube in the middle of the space, you can type CENTER-THROUGH. 00:05:47
And this is the result. 00:06:02
But if you want to translate it sliding the cube, you must use TRANSLATE. 00:06:04
and the vector of translation, for example, 10 or 20, 20, 20, 0, 0. 00:06:24
Be careful when you type, because if you fail, there's only one figure, there's only one vector. 00:06:51
So this is the result of translation. 00:07:02
You can also do a rotation. 00:07:04
This is the result of rotation. 00:07:15
And you can combine rotation and translation as you have in your book. But be careful because they are not, it's not the same. For example if you rotate this is the result and if you do the translation in this way this is the result. 00:07:18
is not the same if you do it in this order than in immersed. So be careful when you do 00:08:15
the difference, the difference operation. Well, apart from this, you can also, you can 00:08:34
also use your design using more than one figure. For example, if you want to create a dream, 00:08:43
must use a difference, the operation difference. For example, I have a cylinder. 00:08:55
This is the cylinder, this is our cylinder, and I want to do a hole in the middle of 00:09:06
this cylinder. So the first thing is create another cylinder, and this is 00:09:40
the result. But if this cylinder is the drill, it must be in the middle, so I'm going to 00:10:11
translate. And now, if I want to create the hole, I must do one logical operation, that 00:10:18
is difference. Be careful because at movements difference aren't something that is the result, 00:10:59
you have the whole. So this is the exercise 5 on page 63. And finally you can join different parts 00:11:36
using union. If you use union, it means that you have not just only two parts, you have 00:11:55
just only one part. For example, if I want to create a complex, as you have in your book 00:12:22
exercise is you have to the parts we have a ceiling we have a one is the 00:12:32
cylinder this is the height and the number of faces is for example three 00:12:44
That's this one. The other is, for example, asmola, and the number of faces is 8. 00:13:28
So we have two figures. We're going to just lay this one. 00:14:34
So this is the result, for example. This is the result. It's a complex figure. 00:15:10
But if I want that this figure is just only one, I must to do the union. 00:15:21
Union is the same, the same of difference, but in this case what you have is just only one figure. 00:15:29
So union of this one, the result is the same but what is the difference? 00:15:37
The difference is in this case is you want to, for example, translate or rotate. You do the translation of the whole object, not just only one part. For example, what you have in your book, rotate, well you have rotation indeed, not translation. 00:15:56
But you can do the translation, for example, or you can do the rotation. That's what you have in your book, the exercise six of your book. 00:16:36
And that is all of what you have in your book, so what I want is that when you finish, you 00:17:04
just do the screen captures of different exercises, 2, 3, 4, 5 and 6, and the screen shoot you 00:17:20
You can paste in a test file and then submit the exercise and it is all for today. 00:17:35
I hope you enjoyed the exercise. 00:17:48
