Defining Custom Elements

You can define custom element types if you'd like to support types of attributes other than those provided by QuickDraw 3D. You define custom attributes as custom elements because attributes are almost always contained in an attribute set, of type TQ3AttributeSet . More generally, you can define custom element types that can be included in a set of type TQ3SetObject .

See "Creating Custom Object Subclasses" for complete details of the methods you need to define to support a custom element type.
