3D Modeling

Hi all,

In my implementation I need to tell whether two geometry entities are parallel or perpendicular with each other in terms of their normal.

Suppose I have the solid model below. face 1 and face 2 are in fact parallel since their nomals are parallel.

Does ACIS have such functions to tell the position between two entities.

Thanks in advance.

You can obtain the normal to a surface (FACE) at a specific position. It's not necessarily the same at every position.  Based on your application, you would have to figure out what it means for two surfaces to be perpendicular.
