Class Description

See also

Class HierarchyEntry.

Description:

This is a utility class for describing hierarchies of shapes. All methods of this class are implemented by the system.

This is used in generating mesh objects from shapes. In order for a mesh object to be generated correctly, nested shapes must be oriented clockwise or counter-clockwise depending on their level of nesting. For example, a donut shape with two circular curves will have the outer shape going counter-clockwise and the inner shape going clockwise. If a third shape was nested inside both of these, its points would be going counter-clockwise.

Remarks

This method adds one entry given its parent.
