[Bf-committers] Google Summer of Code 2016 - Adding CAD functionality to Blender

Fri Mar 4 13:11:50 CET 2016

Your work is amazing Jaume! I guess that it kills a few points from my
initial list (assuming you are going to merge your code with the Blender
master).

Still, I would like to ear some opinions on the first topic of my list
(editor that would allow the user to make ISO-compliant drawings of
individual parts), which I consider the most important. I can implement the
other points as a python add-on.

Does anyone have some suggestion as to who I could contact personally that
could possibly be interested in being a mentor for this?

I will avoid blenderartists for a while, at least until I have more solid
ideas.
