Man, I'm going to have to do a lot of experimenting with the spline modeller. After a couple of attempts, I was able to follow your tut. and make a right-ended forty-five. Thanks! I didn't manage to do the other end, mainly because I couldn't get around the way there seems to be a constraint on the first point on the (purple) sweep path... move one, you move them all...even in 'envelope:free'. Once again, I'm missing something. I'm embarrased to say I've not checked out the back room yet. I'll go there and do the lightsabre tut.
