Hi everybody,

I modeled a sheet metal forming process in which entire blank is partitioned into two regions (Central and exterior regions). Forming tool is considered as a 3D-Analytical rigid body (Revolved Shell) and partitioned into two regions too. According to this process, the head of punch should be tied to the central region of the blank and punch's walls should contact with exterior region.

In interaction module, I can’t select defined regions on forming tool separately as the surfaces and I don’t know why the whole surface of the punch is selected?
