Hi Michael

Thanks for the script, that will be very useful to me and easy to change the names for each project.

Ok cheers for the explaination about making sure my curves touch exactly to avoid joining problems later on. I wasn't aware that creates problems.

Ok
I've redone the fuselage as a simple tubular revolve using the side profile of the aircraft. I've then add the tailhook fairing to the underside of the plane and the two surfaces join Ok. So far so good. I used a two rail sweep to create the fairing underneath the aircraft and then the scaling rail.

Everytime I use the scaling rail I get a little tear in my nurbs surface just near the end. Is this a display error or likely to cause meshing problems later on ? (see attached image).
edit: Just did a check the tear does create meshing problems. I'm pretty certain the scaling rail has a bug as my curves all look good.
