I have to say I am getting addicted to using Google's SketchUp for rendering models. I decided to give it a shot for my new RBG instructions, and I think I have it under control.
While it has some quirks and not as fast as your own hands, it certainly has that cool factor. Of course, we all have to give props to Imperar for the original Knex models.
Do those of you who use SketchUp find that it was easy to get the pieces to fit right? Know of any little tricks to make it easier?
