ok how about this. could one implement lets call it a sketch (or auto geometry mode?) mode that works like sketchup (sorry i can't get over the way sketchup works its spoiled me). now i know i can draw shapes directly on Moi objects such as a cube... but lets say in this mode i draw a line (circle, rectangle...) on a face, i could then extrude (in or out) either part of that face without splitting, booleaning, trimming... like sketchup. of course this wouldn't need to work with curved surfaces (i'm not greedy). Then i could use Moi instead of sketchup, have the perfect excuse to get Moi, and wouldn't have to put up with Sketchup's pitfalls.

Viola; best of sketchup, best of Moi. That would be just about a perfect modeller.

Sorry if i'm getting annoying. Tell me when to stop.
