alright peeps. This has been bugging me for ages so I thought I'd see if you lot know what to do. Right, say I create a curve for the hull of a boat but only one half of it. I duplicate it, rotate it 180 to make it symmetrical, reverse curve direction and attach it to the original curve. It all seems alright until I try and scale the complete curve when only one half responds. But if I duplicate it, the new curve behaves normally. However, after lofting a group of these curves, I try rebuilding the NURBS shell and end up with one end detached from the other. I'll upload a pic tomoz if you can't see where I'm coming from.
