Detailed Description

A TShape is a topological structure describing a set of points in a 2D or 3D space.

A topological shape is a structure made from other shapes. This is a deferred class used to support topological objects.

TShapes are defined by their optional domain (geometry) and their components (other TShapes with Locations and Orientations). The components are stored in a List of Shapes.

A TShape contains the following boolean flags :

Free : Free or Frozen.
Modified : Has been modified.
Checked : Has been checked.
Orientable : Can be oriented.
Closed : Is closed (note that only Wires and Shells may be closed).
Infinite : Is infinite.
Convex : Is convex.

Users have no direct access to the classes derived from TShape. They handle them with the classes derived from Shape.
