This unit of functionality provides the capability to represent geometry as a two-dimensional wireframe model, i.e., of two-dimensional points and curves.
NOTE The difference between 3D and 2D geometric elements is specified by the presence or absence of a third coordinate value.
Composite curves for the geometric representation of paths and loops are included in this UoF. The types of points and curves excluded from this UoF are point_on_surface and curve_on_surface. All unbounded curves in this UoF are explicitly trimmed unless they are closed in order to facilitate the data exchange, the visualization on the screen, and to limit calculation time.
Surface data and all topological information are outside the scope of this UoF.
The following application objects are used by the wireframe_model_2d UoF:
