	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 . It means: proj(C(u)) = PC(u) for each u. Otherwise, the parametrization may change.
