virtual void MemoryRelocate ()
 The MemoryRelocate() function is called when an object's location in memory is changed. For example, if an object resides in a chunk of memory that is grown by calling a realloc that has to allocate a new chunk and copy the contents of the old chunk to the new chunk, then the location of the object's memory changes. In practice this happens when classes derived from ON_Object are stored in dynamic arrays, like the default implementation of ON_ObjectArray<>'s that use realloc to grow the dynamic array. More...

 Uses the destination_manifest to update references to other components.

Detailed Description

Brep vertex information is stored in ON_BrepVertex classes. ON_Brep.m_V[] is an array of all the vertices in the brep.

If a vertex is a point on a face, then brep.m_E[m_ei] will be an edge with no 3d curve. This edge will have a single trim with type ON_BrepTrim::ptonsrf. There will be a loop containing this single trim. Use ON_Brep::NewPointOnFace() to create vertices that are points on faces.
