Hi Steve, I'm glad that helped!

> I assume the same concept would apply to lofted shapes etc.

Yup, the same thing applies there as well - if you have some kind of irregular shaped boundary you probably don't want to try to loft directly to that boundary initially, instead you'd want to make a larger smooth surface and them trim it to produce the final boundary.

Here are a few previous posts with some similar cases where building an extended shape and then cutting it was the best strategy:

You usually want to do this kind of strategy when you've got some kind of surface shape that has looks all nice and smooth but then has an edge in it that suddenly cuts the shape off. It is easy to recognize this when the cutoff is an internal hole in the surface, but the same thing applies when the cutoff is slicing the outer edges of the surface as well.
