Subject: INTERESTING ASD PHENOMENON
>Hi pfAll!

>I have come across a somewhat wierd behavior of the ASD.

>When I prune a face, i.e. erase its childs to make the

>should keep their refverts and their childs. They always
>do this, BUT in certain areas the surrounding faces don't
>show their childs. These wierd faces look as if they were
