WEEK 2 (01 February 2017)
[Computer - Aided Design]

The second assignment for the FabAcademy was about a computer aided design software, here I start thinking about my final project: Automated Cat Feeder, using different tools and environments, like Autodesk CAD 2D and Ilustrator, for 3D drawing Solidworks and i also explored Rhino, these were my first steps with Rhinoceros, looking for geometric generative possibilities and iterations to draw my final project.

In this class session I have started to sketch the cat feeder.

Project Studies in 2D Autocad:

These are my final project studies in 2D , these drawings were made in autocad

These are the profiles of my final project applied, these drawings was made in autocad.

Cad is a tool that I have been working for many years, and that is why I started with this "tool" to have the correct and scale dimensions, and to make this task more easier.

First Steps With Rhino:

It is the first time I'm drawing with Rhino and I'm really liking it, it's very similar to Cad, I've been reading tutorials and even this is going well, I started by creating simple shapes, trying to adapt it to my idea. I "extruded" the 2d shapes to transform them to the 3D object. After having the objects, I did some "Boolean operations" like "booleanunion", "difference" and "split". When I boolean union two solids I get a more complex solid than I might otherwise expect (:

The "BooleanDifference" command trims the shared areas of selected polysurfaces or surfaces with another set of polysurfaces or surfaces. You can do this command in 2 steps:
1.select surfaces or polysurfaces to subtract from, and press Enter;
2.select surfaces or polysurfaces to subtract from, and press Enter;

I did an extrude curve, for the tubes, I drew the circles, extruded them and make a "bollean difference" to take them of.
I made each face in a different layer and with a different color to identify them more easily. The "extruve curve command" creates a surface by tracing the path of a curve in a straight line.
You can do this command in 2 steps:
1.select a curve;
2.specify a distance:

Project Studies in 2D Ilustrator:

I used Ilustrator to draw the written parts of my project, which I want to build in acrylic, and I also drew de logo of the final project.

3D (Render) of my Final Project :

These are my final project 3D Renders, these drawings were made in KeyShot. It was the first time I used KeyShot to render, it's very easy and very similar to "Artlantis", which is another program that I use to render.

First step: I opened the Keyshot and made "Import" from Rhino file;

Second Step: In this step I will choose a material to apply on the different layers of my project;

Thirt Step: Then I drag the materials and textures to the 3D object;

Four step: We go to "render" menu and choose render command

Final result:

3D Animation of the Final Project

It was the first time I did an animation with Rhino, and it was quite easy with 7 quick steps, I made a video in Rhino:

- Control Point Curve;

- Create a Single Point;

- Make some Points On;

- Lock Object;

- Make a Set Up Path Animation;

- Choose 180 frames;

- Press Play;

Watch the VIDEO:
