Polyextrude edges, how to extrude towards the interior of a polygon

Recommended Posts

I would like to have primitives 1 2 and 3 cut into primitive 0 after this operation. Basically the same way it works in 3d when you use polyextrude to create a cavity in a solid (output front and side)

One kludgy solution I found is to triangulate the result and constrain the triangulation to include all edges, then delete corresponding faces in the result, but it's going to break easily.

So what is a good solution to this ?

tbh, not sure what the hell I'm doing here but seems to work :D

(still got the overlapping problem tho)

ahh easy...

(and I would expect this NOT to work for non planar objects)
