Loft issue

Hi,

I’m trying to loft multiple curves, and I get an open brep with some issues (shaded end of the brep). However, when I loft the curves by segments (which is what I actually want to achieve), the output brep is smooth.

What could be the reason for this issue?

Loft list of curves:

Loft pairs of curves (segments) and join them:

I’m not at my computer.

Are the curves in order? If not, try sorting them.

Well, the point order was not the issue because it was correct. However, while checking the order once more, I realized that the last curve was duplicated. The duplicated curve in the loft list caused this problem. Thanks, Martin, for the hint.
