Enumerations

enum  TopAbs_ShapeEnum {
  TopAbs_COMPOUND, TopAbs_COMPSOLID, TopAbs_SOLID, TopAbs_SHELL,
  TopAbs_FACE, TopAbs_WIRE, TopAbs_EDGE, TopAbs_VERTEX,
  TopAbs_SHAPE
}
 Identifies various topological shapes. This
enumeration allows you to use dynamic typing of shapes.
The values are listed in order of complexity, from the
most complex to the most simple i.e.
COMPOUND > COMPSOLID > SOLID > .... > VERTEX > SHAPE.
Any shape can contain simpler shapes in its definition.
Abstract topological data structure describes a basic
entity, the shape (present in this enumeration as the
SHAPE value), which can be divided into the following
component topologies:

Enumeration Type Documentation

  • COMPOUND: A group of any of the shapes below.
  • COMPSOLID: A set of solids connected by their
    faces. This expands the notions of WIRE and SHELL to solids.
  • SOLID: A part of 3D space bounded by shells.
  • SHELL: A set of faces connected by some of the
    edges of their wire boundaries. A shell can be open or closed.
  • FACE: Part of a plane (in 2D geometry) or a surface
    (in 3D geometry) bounded by a closed wire. Its
    geometry is constrained (trimmed) by contours.
  • WIRE: A sequence of edges connected by their
    vertices. It can be open or closed depending on
    whether the edges are linked or not.
  • EDGE: A single dimensional shape corresponding
    to a curve, and bound by a vertex at each extremity.
  • VERTEX: A zero-dimensional shape corresponding to a point in geometry.
