Hi and thanks for the replies, ttype (STRUBE) and Michael.

Michael.

I'll give Loft a good try on the job I'm doing. With a bit of fiddling, it might well do what I need.
I must say that I never thought to try Loft as I didn't realise it would work with 3D curves - but I know now:)

Thank you very much for taking time out to see if this is possible to do and I hope luck's on our side.


Martin.
