How do I align the control planes at divide points on a circle to have the curves at those points normal to the circle? in the case of my definition those curves are circles. At this point i am only attempting to make a donut and then play with it. I can sweep just one curve but want to divide it next - or take a bite out of it. This is a learning exercise for me.
The solo components in the definition have been tried without success.
Thanks for the help
