Thanks for the tip! But I think that won't do the trick.
http://www.conitec.net/beta/aent-vec_for_vertex.htmThis is great to simulate a lot of things, though..
If I could delete a single face of an entity I can simulate digging holes from there! delete face -> fill the gap with *this model* (to pretend it's a hole)
But I don't have anything specific in mind! This is just me playing around
