A3DTopoEdgeData

struct A3DTopoEdgeData

Edge structure.

2.0

• A3DTopoContextData::m_dTolerance member for the entity
• Tolerance
• See note about orientation in Topology Module.
• If the m_p3dCurve member is null, either the edge is degenerated or all co-edges have UV curves.

When parsing this structure, use a tolerance that is the greatest of these values:

Variables

A3DTopoVertex *A3DTopoEdgeData.m_pStartVertex

A3DTopoVertex*

Start vertex; can be either an A3DTopoMultipleVertex or an A3DTopoUniqueVertex.

A3DTopoVertex *A3DTopoEdgeData.m_pEndVertex

A3DTopoVertex*

End vertex; can be either an A3DTopoMultipleVertex or an A3DTopoUniqueVertex.

A3DCrvBase *A3DTopoEdgeData.m_p3dCurve

A3DCrvBase*

Pointer to 3D space curve.

A3DBool A3DTopoEdgeData.m_bHasTrimDomain

A3DBool

A value of true indicates the edge has a trim domain.

A3DIntervalData

Trimming domain for 3D curve.

A3DDouble A3DTopoEdgeData.m_dTolerance

A3DDouble

Edge tolerance.
