Morph between 2 curves if you have the Multiaxis ability. Tell it in axis control 3 Axis. I used the Extend/Trim on the Cut pattern Page. I then extended the start and exit .02 to have it come off and on the edges .02. I also used Orthogonal entry and exit on the linking and changed it on the default lead-in/out.  Here is the link for the file from dropbox.

These toolpaths were never really meant to do undercuts IMHO. They are still excellent toolpaths and gets the job done, but I have had to do like John suggested before on undercuts. Nature of the beast so to speak.

The problem is not the parameters in the direction dialogue box, it is the nature of the surface being used.  The file I looked at was made of  trimmed nurb surfaces.  When I opened the flowline data parameter for the surfaces being used it was plain as day that the surface had some irregularities that was causing the lead-out to crash through the  part.

I made a solid using the geometry available and then attached the tool path to this new surface and then re-gen.  Problem solved. 5b0ed2ff802bd_goodflow.thumb.jpg.ada124e2db30abf19f726516e24cea95.jpg

Hope that helps.
