This a generic class is used to build Sweept primitives with a generating "shape" and a directing "line".
The indexation and type analysis services required for the generatrix are given by <Tool from BRepSweep>.
The indexation and type analysis services required for the directrix are given by <NumShapeTool from Sweep>.
The iteration services required for the generatrix are given by <Iterator from BRepSweep>.
The iteration services required for the directrix are given by <NumShapeIterator from Sweep>.
The topology is like a grid of shapes. Each shape of the grid must be addressable without confusion by one or two objects from the generating or directing shapes. Here are examples of correct associations to address:
- a vertex : GenVertex - DirVertex
- an edge : GenVertex - DirEdge
- : GenEdge - DirVertex
- a face : GenEdge - DirEdge GenFace - DirVertex ...
"GenObject" is used to identify an object from the Generating Shape, and "DirObject" from the Directing Shape. So may they be from different types.
The method Has... is given because in some special cases, a vertex, an edge or a face may be geometricaly nonexistant or not useful.
