Modeling a quadruped robot from parts to full assembly with SolidCraft and HappyCAD

A developer used SolidCraft and HappyCAD to model each part individually and complete the full assembly of a quadruped robot, and also made an animation showing how the components fit together. The main body shell took the longest, with the difficulty lying in handling the mounting points and clearances around the leg joints. The author is asking for direction on what to refine next: part modeling or assembly setup.
