Week2: Computer-aided design 

This week we must make an aproach to the final design, making sketches of our proyect. I will try all the programs of the list and make some thoughts about them.

PAPER and PENCIL
My first approach to sketching is always a pencil. Ergonomic, simple, confortable...the pressure control is my favourite feature :) Here is my first sketch:

GIMP-PHOTOSHOP

I dont want to put them in the same bucket, but they all make the same thing. Ive been working with photoshop so many years ago, and its my first option in photo editor. Gimp over windows make a nice approach in 2.8, above all the new unique window appareance, just like photoshop and other photo editors. But who used to work over photoshop, has a hard learning level over Gimp.


My Paint

This is my great discover in the program-list. I love to make sketches in My paint, because  has this paper-look-like that makes me feel confortable. The brushes are great and have a lot of options to work with it. Maybe an eraser tool with a direct button was a great idea. Heres my sketch with this software:

TINKERCAD

I have been working in the past with this online 3D tool design. Its a wonderful approach to the 3D world, and a nice tool to begin in 3D printing. Its a kind of sketch in 3D, and with very simple primitives you can make a great 3D model to print it out. Maybe its too many simple to get a great result in 3D modeling, but its a fast and simple tool. I like it.

RHINO and BLENDER


And finally here are the professional tools to work in 3D. The two solutions al really valid to work with 3d, in our Fab Lab we had Rhino, but this time i want  to try Blender to model a simple R2D2. Maybe i need more time to get confortable with the tool, im a bit confused with the working camera, but i think with more practice i will do much better.

THE NEXT STEP...


Is to start with the parametric programs like FreeCAD and Fab Modules.
