Follow arc problem

I’m trying to use the Copy along Vector tool in VCarve Pro but I’m having problems and need some help. I’m an advanced user, but this has me stumped.
See the attached pdf.
Thanks,
Pony

Thanks to Vectric support, I have the fix for my problem with Copy along Vectors tool. It’s nothing I would have ever figured out by myself and is definitely not documented.
