Hi Lars, you're welcome, I'm glad that you have a technique that will work for you now.

To make the edges less wiggly the original lofted surface needs to get a bit smoother.

It can be tough to smooth things out at inflection areas and where things kind of stack up.

One thing you might try for that is to use a smaller number of sections - sometimes too many sections tends to kind of "overconstrain" things and introduce more wiggling.

The other thing that can be good to experiment with is using the Loft Style: Loose option - that will create a Loft that does not directly pass directly through your section curves (except the first and last one) but it will tend to be much smoother and less wiggly.

You may find the best result by using Loft Style : Loose and then kind of slightly expanding the sections other than the start and end one to kind of compensate for the slight "shrinking down" type effect that loose style creates. It's a lot smoother though and it isn't as sensitive to having a larger number of sections.

Hi Michael, the loose option seems like a good idea. However, now I no longer can use the blend feature to create a closed surface..

Edit: just read the help file: Note that if you have independent curve objects overlapping your surface edges (for instance some of the original curves used to build the surface), it is easy for those curve objects to get selected when you click instead of selecting the edge of the surface. It may be necessary to delete or hide these original curves so that the edge of the surface object can be selected instead, that is an easy problem to run into when using Blend.

Hiding those original curves and then blending the edges of the surface did the trick.
