[Bf-funboard] Automatic Edge Bevelling

[Ton Roosendaal]

Hi,

In my sketchbook I have a couple of pages with drawings and notes to  
research how to do this within the current EditMesh context. I think  
it's feasible... but don't know yet if this is something that's much  
faster to do than adding a new 'Manifold' object type, which uses  
winged-edge modeling. A beveling feature as you describe is almost a  
built-in feature for winged-edge systems!
