"Instead of drawing a completely new path curve, you can just re-use the existing surface edges - that's the easiest way to ensure that your sweep hugs them exactly.

To do that, select all those edges that go around one loop and then use Edit/Join to glue them together into a single new curve - you can then use this new long curve as your path curve instead of trying to manually draw a new path curve."

Of course!!!! And, that is brilliant!

Yep, I knew it was me. Hey, I got *that* right, at least.

Thanks, Michael.
