In this Assignment, I'm trying to use Onshape to do one of my previous project that done by Inkscape. The goal was to be able to edit the design if you change the material like thickness and also it can be assembled in a different way. However, I did rescale the design by Onshape to print and cut a small prototype for testing the ability that program gives me. .
After that I did export the deisgn to DXF format from Onshape and open it via Inkscape.
Onshape and Inkscape a great combination that you implemented a different design.
It's including the 3D printing for the shelf I have made
