Detailed Description

group a3d_multiple_vertex

Entity type is kA3DTypeTopoMultipleVertex.

A multiple vertex is defined as the average position of several 3D points, which are typically the endpoints of edge curves that end at this vertex.

Warning

In general, no constraint is given to the 3D points stored in the array referenced by the A3DTopoMultipleVertexData::m_pPts member. In particular, the same point (same coordinates) may appear multiple times in that array. This is a common behavior, and all these points must be taken into account to evaluate the tolerance.
