I'm working on an assignment for class. When I use a standard pocket toolpath to pocket out a slot everything runs fine, when I change to a "slot mill" I get the following error: "Boundary must consist of two parallel lines connected by arcs, Use Create Rectangle with Rectangular Shape set to obround." I have no clue what that error message is trying to tell me. If asked the question "what is the difference between a standard pocket and a slot mill pocket" I would be forced to admit I have not idea. Clearly I belong in the newbie corner. Any help would be appreciated. Fred Hunt Coos Bay, Oregon

Personally I think the videos at http://www.eapprentice.net are rather fabulous. It's the best $25.00 a month I've spent in a long time.
