Hello,
I am a 3d artist who has a lot of technical drawing, Cnc, laser, plotter cutting experience.
I opened your sample file. Instead of rendering ( which is not accurate way ) i can generate vector file from directly 3d model.
I can deliver as .cdr, .eps, .ai, .pdf(preferred) format.
I can deliver four models in a day ( for similiar models ).
Glasses in the .blend file has a small bend. I can generate unfolded version of the shape. Or i can ignore the bend of the glasses and simply project into 2d vector. Which one is work for you, it is ok for me.
It would be good how you will use the vector ( will you cut directly on a laser or cnc? will you print, transfer on a wood and hand carve? etc... )
Thanks,
Kadir.
