Is there a way to extend the loft of an object to a plane so that I can use it as the lower profile for a 4-Axis wire burn? I am having trouble extending the surfaces and the wire EDM software only deals with 2D geometry with a Z axis. Ie. lines and arcs at z0 and at z+#. I was unable to attach the file. If you would like to see the file, please let me know. Thanks.
