static Curve2d()

• gives the 2d-curve of a 3d-curve lying on a surface ( uses GeomProjLib_ProjectedCurve ) The 3dCurve is taken between the parametrization range [First, Last] <Tolerance> is used as input if the projection needs an approximation. In this case, the reached tolerance is set in <Tolerance> as output. WARNINGif the projection has failed, this method returns a null Handle.

static ProjectOnPlane()

• Constructs the 3d-curves from the projection of the curve <Curve> on the plane <Plane> along the direction <Dir>. If <KeepParametrization> is true, the parametrization of the Projected Curve <PC> will be the same as the parametrization of the initial curve <C>. It meens: proj(C(u)) = PC(u) for each u. Otherwize, the parametrization may change.
