OdDbBlockBegin Class

Syntax

C++

class OdDbBlockBegin : public OdDbEntity;

Description

This class represents BlockBegin entities in an OdDbDatabase instance.

Remarks

OdDbBlockBegin entities are created and handled automatically for each OdDbBlockTableRecord object.

Client applications may add extended data or extension dictionaries to these entities, but should not create or delete them.

These entities have no associated geometries.

Do not derive from this class.
