3.6.15. Topology Changes and Entity IDs

Modifications to the geometry can result in a change to the number or ordering of edges, faces, or bodies of a solid. Various constructs in Analyst depend on this numbering to function properly (for example; attributes, blends, face translations, and face coordinate systems).

Analyst detects such changes and typically correctly adjusts these constructs automatically. If this fails, however, Analyst removes these constructs or places them in an error state. In either case a warning is generated to make it clear that you should review the structure for problems.

The following examples better illustrate this behavior.
