It doesnt do it on spline, correct?
Yes it will work on a spline also Nuno.
I tried on a spline and it didn't work... maybe my curves were to short for the circle.
I am not sure what you have done Nuno.....
But it does work on a spline...
Send me your part file over with the spline you are trying it with and I shall have a look and see if we can get to the bottom of your problem.
Is there any other tutorials I could do to help you and the community with Nuno?
