deferred class TShape from TopoDS inherits TShared from MMgt
---Purpose: A TShape is a topological structure describing a
-- set of points in a 2D or 3D space.
--
-- 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.
-- - 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.
