Weird Toolpath Lifting issue on Parallel and Scallop

[greg.vinyard915]

I am attempting to run a parallel toolpath on a part that comes to a point, basically a knife and I have never seen this issue before and it hasn't occurred in any of my other files. The end of the tool path lifts up and avoids the tip (see Screenshot). This occurs on both Scallop and Parallel. Can someone point me in the right direction? I checked against other files and I'm not seeing the behavior in my other fusion files. parallel toolpath problem.png

We need to see the Fusion design to know more. Its usually modeling related but could be numerous things.

Would it be easier if I uploaded the .F3d file?

Yep! or share a public link to the design. Whatever works for you.

There is a small sliver face on the tip of the blade that is causing this:

Delete it and it will generate just fine. This happens quite often with knife blades when the sweep path does not extend far enough. Often what i'll do is use a sketch with a slight extension of the blade profile.
