VC and variable streamline

Have some trouble getting a clean variable surfacing path. Any suggestions? I have tries Variable couture and variable streamline with several projection vectors and tool axis combo’s.

The area is a conical shape with a tapered rib going around it. The real issue I’m having is getting a semi consistent stopover in order to get a good surface finish on the part.  surface area is un-able to create drive geometry due to chaining tolerance



Re: VC and variable streamline

I've used contour profile with multiple passes in situations like this. I know its "off label" but if nothing else is working...

In streamline, I would be sure you have cross curves joining the 2 loops where each corner starts and ends. Next would be to increase the Cut Step.
