20 //! Identifies various topological shapes. This
21 //! enumeration allows you to use dynamic typing of shapes.
22 //! The values are listed in order of complexity, from the
23 //! most complex to the most simple i.e.
24 //! COMPOUND > COMPSOLID > SOLID > .... > VERTEX > SHAPE.
25 //! Any shape can contain simpler shapes in its definition.
26 //! Abstract topological data structure describes a basic
27 //! entity, the shape (present in this enumeration as the
28 //! SHAPE value), which can be divided into the following
29 //! component topologies:
30 //! - COMPOUND: A group of any of the shapes below.
31 //! - COMPSOLID: A set of solids connected by their
32 //! faces. This expands the notions of WIRE and SHELL to solids.
33 //! - SOLID: A part of 3D space bounded by shells.
34 //! - SHELL: A set of faces connected by some of the
35 //! edges of their wire boundaries. A shell can be open or closed.
36 //! - FACE: Part of a plane (in 2D geometry) or a surface
37 //! (in 3D geometry) bounded by a closed wire. Its
38 //! geometry is constrained (trimmed) by contours.
39 //! - WIRE: A sequence of edges connected by their
40 //! vertices. It can be open or closed depending on
41 //! whether the edges are linked or not.
42 //! - EDGE: A single dimensional shape corresponding
43 //! to a curve, and bound by a vertex at each extremity.
44 //! - VERTEX: A zero-dimensional shape corresponding to a point in geometry.
