Thanks for the replies.

TwinSnake: Wierd, i tried really small values for it but still no joy - are u using v1.0?

Michael: Thanks! I think it`s testament to the software that it can be picked up so quickly. Really useful for as u say man-made objects, but more specifically products, prototypes, cars, planes, mobile phones and things like that. Things that can be modelled more efficiently and fluently using nurbs as opposed to hand-sculpting polygons (no matter how good the poly-tools). I`ll maybe give the beta a bash given what you`ve said..
