The Guide Curves functionality requires the selection of 2 curves designated with the starting points, and a selected solid or faces to machine. The direction of cut is set by the selected points. In the following examples we have a One Way cut designated as starting at the top left point and a ZigZag cut designated to start at the bottom right point. The One Way cut will continue to cut in a downward direction while ZigZag will alternate
A Guide Curves Plunge Rough operation using an Up Hill pattern behaves similarly in that it will go from the first selected point to toward the second point, breaking the motion as needed, to go up hill
