The AcDbAttributeDefinition class represents the ATTDEF entity within AutoCAD. ATTDEF entities are used within block definitions (AcDbBlockTableRecords) for AutoCAD to use as templates for creating ATTRIB entities (AcDbAttribute objects) when an INSERT (AcDbBlockReference) is created that references the block definition.
To set all the non-AcDbAttribute-specific properties such as position, text string, text height, text rotation, etc. for the attribute, use the methods inherited from AcDbText.
