Thanks for replying - sorry I havent writen back earlier, been away the last couple of days.
"One way you might could try is by using an extruded shape along a path (Surfaces > Extrude. Ask if you don't know how to use it), but check the "Partial" option in the option box."
Ok first question - I created a path with the CV curve tool but not sure how to go from there, do I create a primative shape and try to extrude that??
Hope you can help!
