Understand Properties and Methods

Each object has associated properties and methods. Properties describe aspects of the individual object, while methods are actions that can be performed on the individual object. Once an object is created, you can query and edit the object through its properties and methods.

For example, a Circle object has the Center property. This property represents the 3D world coordinate system coordinate at the center of that circle. To change the center of the circle, simply set this property to the new coordinate. The Circle object also has a method called Offset. This method creates a new object at a specified offset distance from the existing circle. To see a list of all properties and methods for the Circle object, refer to the Circle object in the AutoCAD ActiveX and VBA Reference.
