This unit of functionality provides the capability to represent geometry as a topologically connected geometric model consisting of solid, surface, or wireframe data. This geometric model deals with mixed dimensionality (solids, surfaces, and wireframes) and non-manifold topology.
Only shape models with complete topological description, i.e., in boundary representation are supported. Since the topology is not restricted to be manifold, the models can have more than two faces sharing one edge, and faces shared by two adjacent shells. A compound representation collects several geometric items of the same or of different type and joins them into one topologically connected model.
NOTE This UoF should be used wherever portions of the shape have to be distinguished.
EXAMPLE Examples for distinguishing portions of the shape are material zones with different heat treatment, structures welded together, meshing macros for finite element analysis, and shape representation of varying dimensionality, e.g., surfaces and solids.
This UoF includes all application objects of UoF b_rep_model (G5) and connected_surface_model (G3).
The following application objects are used by the compound_model UoF:
