In this workshop, Anool Mahidharia takes the output of KiCad’s VRML export, gets it rendering in Blender, and then starts tweaking the result until you’re almost not sure if it’s the real thing or a 3D model. He starts off with a board in KiCad, included in the project’s GitHub repo, and you can follow along through the basic import, or go all the way to copying the graphics off the top of an ATtiny85 and making sure that the insides of the through-plated holes match the tops.
If you don’t know Blender, maybe you don’t know how comprehensive a 3D modelling and animation tool it is. And with the incredible power comes a notoriously steep learning curve up a high mountain. Anool doesn’t even try to turn you into a Blender expert, but focuses on the tweaks and tricks that you’ll need to make good looking PCB renders. You’ll find general purpose Blender tutorials everywhere on the net, but if you want something PCB-specific, you’ve come to the right place.
