Computer-aided design

Have you:

  • Modelled your proposed final project in 2D and 3D software
  • Shown how you did it with words/images/screenshots
  • Included your design files

Shown how you did it with words/images/screenshots

For this assignment I had to choose among many software for 2D and 3D design, so I chose:

  • LibreCAD
  • Tinkercad
  • OnShape
LibreCAD for its similarity to AutoCAD and Tinkercad for its ease of use. I think Tinkercad has limitations, I have not yet discovered how to make holes in one of the layers of my design. Then I try with Blender, SketchUp or Inventor.
LibreCAD was easy to install on Ubuntu.


To learn LibreCAD I checked the tutorial and some videos of Youtube.



This is the sketch of my 2D design.

The 3D design was easier, although some details still do not know how to do. Isaac Robles explained how to use Tinkercad and that helped a lot.
You just need to create an account on the website of Tinkercad. The model is derived from the union and subtraction between solid objects.




OnShape
First you must design a pattern. I tested the "OnShape" software to design a puzzle.


You can create a sketch like any software 2D design and then export it in dxf format.






I designed another piece and then assemble the pieces to test the joints.




Included your design files
