2. Computer-Aided Design
Now we are gonna learn about design, or at least put in practice some of the stuff I learnt this week
Let´s get some design done (1st step)
My mission was to get like a watermark, I´m aiming to use it for all my projects, something like a personal logo
I remembered i used to hace an unicorn I loved in primary school, so i looked for it, and found it, i just wanted to
use it as a reference.
So, I took a picture with my phone...
![](../assets/images/uni (1).jpeg)
Now, I used that image to draw over it, i decided to use Illustrator, so I opened a new file, and inserted the image
![](../assets/images/uni (7).jpeg)
![](../assets/images/uni (5).jpeg)
And, started to use the pen tool, to draw over it, i discovered, I am not as good as I thought I would be hahaha
And this is what i got:
![](../assets/images/uni (4).jpeg)
But that was only the beggining, i wanted a different pose, so i selected the head, and turned it around
![](../assets/images/uni (3).jpeg)
Ereased the original one, and inserted the new head, now it has a different pose, and I added some eyes, to make it
look cute
Saved it as png and it was ready to go.

SOME 3D NOW
Okay, so I´m something like a collector of diecast cars, and i wanted to do like a base to display them
The reason for it, is that my cars are always rolling around whenever I put them in a solid surface
So I took some measurements:
![](../assets/images/car (2).jpeg)
![](../assets/images/car (1).jpeg)
![](../assets/images/car (3).jpeg)
![](../assets/images/car (5).jpeg)
With those, I got my main measurements: I was gonna need a rectangle of 10 x 5 cm, the wheels are about 4mm
and since I wanted it centered on the base, I needed do leave something close to 2.5 cm from the center to the rest area of the wheels.
So, with those, I got hands on it, first thing, open Catia then start> mechanical design> part design

Now, naming the project, I just named it caballo for no reason at all
![](../assets/images/carca (11).jpeg)
I selected the xy plane to work, just click on it
![](../assets/images/carca (9).jpeg)
Used the rectangle tool, to make the base of it
![](../assets/images/carca (8).jpeg)
Used the rectangle tool, to make the base of it, and went out of the sketch
![](../assets/images/carca (8).jpeg)
Next, used the pad option to give it 3mm of volume
![](../assets/images/carca (6).jpeg)
Got my base!
![](../assets/images/carca (7).jpeg)
Made a new sketch over the last rectangle, and drew the little holes where I´m gonna set the wheels of the car
![](../assets/images/carca (4).jpeg)
Used the pocket tool, and just used 1mm cause I dont want to hide too much of the wheels

Lookinnnn´ fineee

And something like my first hero shot, this would look like, when I print it in 3D, I think we are gonna learn that eventually
