BRepSweep_Trsf Class Referenceabstract

This class is inherited from NumLinearRegularSweep to implement the simple swept primitives built moving a Shape with a Trsf. It often is possible to build the constructed subshapes by a simple move of the generating subshapes (shared topology and geometry). So two ways of construction are proposed : More...
