Untitled.3dm (416.5 KB) I’m trying to make a connection between the edges of these circles, but for some reason it keeps twisting like this. I’ve tried to do it with just two circles and that works, so I guess the issue is my surface, but I don’t know how to solve it, I would really appreciate some help!
If you use proper degree 5 circles as part of the vertical and horizontal surface construction, BlendSrf works as it should.

If you use a simple Loft, manually matched on both boundaries, you even get an equal isocurve distribution as a “bonus”.
yes, but…. it should work without any fussing..
definitely a bug in there somewhere that need squishing.
(also you can use the match tangency start and match tangency end in loft and get a lovely surface without any extra matching)
This bug needs fixing. In the mean time, if you make sure that the upper trim curve seam is more or less in the same location as the lower surface seam, and both are oriented in the same direction, BlendSrf finds the correct shape. BlendSrf will then let you adjust the seam location as well, and this does not happen in the original file.
In the attached I have re-trimmed the upper shape with the curve and I’ve annotated the trim curve seam and the surface seam, and their directions.
As said, this needs fixing, but it can be done.

@Lagom’s solution:
- Rebuild the original curves (bottom and top circles) that you use to make both surfaces (degree=5).
- Use BlendSrf to create your desired column
