Object Properties
 
 
 

All objects in the AutoCAD object model have one or more properties. For example, a circle object can be described by properties such as radius, area, or linetype. An ellipse object also has area and linetype properties, but it cannot be described in terms of its radius. Rather, you describe it in terms of its major to minor axis ratio, a property named RadiusRatio. Property names are necessary when accessing AutoCAD data through ActiveX functions.
