Adaptor3d_SurfaceOfLinearExtrusion Class Reference

Generalised cylinder. This surface is obtained by sweeping a curve in a given
direction. The parametrization range for the parameter U is defined
with referenced the curve.
The parametrization range for the parameter V is ]-infinite,+infinite[
The position of the curve gives the origin for the
parameter V.
The continuity of the surface is CN in the V direction.
