Wireframes of my Revo model.
Started from a basic primitive objects (box, cylinder etc), and applied 2-4 steps of bevel/chamver to smoothen it.
Im avoiding to use any subdivision/meshmooth on the body and turret, so I can spend more of details on the other parts (tracks, wheels, modeled rivets nuts etc).
No boelean on the holes, all were manually cutted.
