Both methods have worked well lads.

Michael with a bit of trial and error to get a more square end as it approaches the ends works okay.

Eddi, a bit more work but a nice finished result. I have only used your version as a render as not sure how you have done it yet, is this possible in V2?.

I work primarily with Turbocad, but find that some things are better done in Moi as some of Michael's routines are very flexible plus Turbocad and Moi file interchangeability works spot on.
