Contact Point Boundary - Morph Toolpath

[rmsmachine]

Guys, I am working on a simple mold and am having trouble get the Morph tool path to not roll over the edge.  I was always able to use contact point boundary to eliminate this in the past.

I have attached an example file for you to see what I am talking about.  The actual part has a 45° bend in the middle.

I have tried all sorts of things and can't quite find the right combination to eliminate those unneeded toolpaths rolling over the top edge.

Let me know what your thoughts are.......

Odd, looks OK here, I reduced the stepover and it still doesn`t go over the top and extended the "Additionat Offset" and it goes to the ends but not over the top so I am not seeing a problem. Maybe I am looking at the wrong area ???

The reason contact point boundary isn't working is you have your containment set to "Silhouette"

You need to actually select a boundary  for contact point boundary to work

Check out the attached file, I also added a blend toolpath to look at as morph doesn't do well in the steep areas, whereas blend has a consistent stepover over steep/shallow curvature

Thanks for the response and fix!!!

I have not tried it personally yet (won't be at my computer for a bit) but your picture shows what I expected when using contact point boundary.  

If I have any issues, I will post them up, thanks again!!!

Well, I guess I can't get it to work 😔

Could someone take a quick look to see what I am doing wrong?  I drew a boundary like was suggested and that did not seem to work.  I tried the blend toolpath but I have never used that before and couldn't seem to get anything to generate.

It can't be that hard but I can't seem to get this darn thing figured out on my own!!!! 😠
