0020 //! Identifies various topological shapes. This
0021 //! enumeration allows you to use dynamic typing of shapes.
0022 //! The values are listed in order of complexity, from the
0023 //! most complex to the most simple i.e.
0024 //! COMPOUND > COMPSOLID > SOLID > .... > VERTEX > SHAPE.
0025 //! Any shape can contain simpler shapes in its definition.
0026 //! Abstract topological data structure describes a basic
0027 //! entity, the shape (present in this enumeration as the
0028 //! SHAPE value), which can be divided into the following
0029 //! component topologies:
0030 //! - COMPOUND: A group of any of the shapes below.
0031 //! - COMPSOLID: A set of solids connected by their
0032 //! faces. This expands the notions of WIRE and SHELL to solids.
0033 //! - SOLID: A part of 3D space bounded by shells.
0034 //! - SHELL: A set of faces connected by some of the
0035 //! edges of their wire boundaries. A shell can be open or closed.
0036 //! - FACE: Part of a plane (in 2D geometry) or a surface
0037 //! (in 3D geometry) bounded by a closed wire. Its
0038 //! geometry is constrained (trimmed) by contours.
0039 //! - WIRE: A sequence of edges connected by their
0040 //! vertices. It can be open or closed depending on
0041 //! whether the edges are linked or not.
0042 //! - EDGE: A single dimensional shape corresponding
0043 //! to a curve, and bound by a vertex at each extremity.
0044 //! - VERTEX: A zero-dimensional shape corresponding to a point in geometry.
