Hi Jean-Paul, do you have an example model of a sweep that you found frustrating that you could post?

It's always helpful for me to see actual model examples rather than just some text description.

But Sweep does tend to have more numerous "forces" applied simultaneously, which can sometimes tend to make for problems. Using fewer profiles and trying to avoid forcing a single surface through too many changes in shape can help to make a more relaxed surface in general.
