While there are often several different ways to create the same graphical object in AutoCAD®, ActiveX Automation offers only one creation method per object.
For example, in AutoCAD there are four different ways you can create a circle: (1) by specifying the center and radius, (2) by two points defining the diameter, (3) by three points defining the circumference, or (4) by two tangents and a radius. However, in ActiveX Automation there is only one creation method provided to create a circle, and that method uses the center and radius.
