Could you explain the "face" line in an ASC file? For example: Face 0: A:0 B:1 C:2 AB:1 BC:1 CA:0 Everythings kosher up to the AB:1. I assume these deal with the normal, but I could yet again be making false assumptions. Thanx, LAM

Sure Larry, AB:1 means that the "edge" from A-to-B is visible. BC:1 means that the edge from B-to-C is visible. And CA:0 means that the edge from C-to-A is invisible. The normals are always derived from the order in which the faces is triangulated. If it's triangulated in counter-clockwise order, the normal faces towards you. Hope that helps… – G
