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 :

Detailed Description

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 : 


     - sharing  basis elements  (the generatrice can be <br>
     modified , for  exemples  PCurves can be added  on <br>
     faces); <br>
