Hi Psygorn, yes that is the down side of having sweep rails that come together to a single end point. You can't use "Maintain height" anymore because it would form a collapsed vertical line at the end instead of it going down into a point. Hmm I wonder if I can tune this up so that it only ignores it for the area past the last profile when there are multiple profiles instead of it being turned off for the entire sweep.

A different method that can be good for blobby smooth capped ends is Construct > Loft using Loft type = "Loose" with a closing point as in the attached version.
