Based on          IFC2x3

Initiator            ISG Meeting-Berlin

Effects              Extended Coordination View

Date                    2006 02 24

Description:

The previous implementer agreement (back to 1.5.1 time) that the opening thickness can be extended by the receiving application in order to create a through hole, is revoked. The sending system is required to always export the sufficient extrusion depths.

Using of a sensible epsilon value by the recieving system to avoid left-over faces due to numeric stability problems is allowed and anticipated.
