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 modified , for example PCurves can be added on faces);
copying everything.
