Specifies the insert units saved with the block.
The object or objects this property applies to.
The InsUnits property specifies the native units for the block reference as defined by the block author. When a block is inserted in a drawing whose units have been defined, the block is automatically scaled proportional to the InsUnitsFactor, the conversion factor between the block units and the current drawing units.
Note To access this property, use the IAcadBlockReference2, IAcadExternalReference2, or IAcadMInsertBlock2 interface.
