Projection onto Plane (3-D FFS)

3-D FFS > From c-edge > Extru

You use the functions of this pull-down menu to create a freeform surface by projecting an already existing c-edge onto an arbitrary plane.

You have the following options to define the projection plane:

	Identification of a plane, via 2 edges,
	Identification of 1 edge and 1 point,
	Identification of 3 points,
	Determination of a surface, (The plane will be determined by the normal vectors.)
	Selection of a processing plane

The projection can be perpendicular or oblique. For a perpendicular projection, identify the required c-edge, which is then projected onto the plane. For an oblique projection, specify a displacement vector. The freeform surface is created by linear connection of the control points of the original c-edge with those created by the projection.

The c-edge can belong to a (planar) sketch or a 3-D sketch.
