Toolpath being cut

[Dick_axford_HBCSV]

Good morning,

I'm having an issue where I'm trying to ballnose a surface and no matter the toolpath, Morph, Geodisc or flow it always is being cut off in the same place, but the drive surface or rails being selected are either continuous or not broken.

I can't share the CAD so I'm looking for any ideas what causes this issue?

Many thanks
