class SurfaceOfLinearExtrusion from Adaptor3d inherits Surface from Adaptor3d
--- Purpose: 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.
