How do I handle Sweep2 problems? Srf Blending problem

[NiklasG (Niklas)]

Hello there, rhino beginner here
I have a more or less complected cross-section where 3 blended surfaces meet each other.
With my last Sweep2 command I now get this surface blending problem:

what is causing this artifact?

Hi Niklas - it looks like those edges there are slightly out of tolerance and not joined. You can clean up like so:

RemoveMultiKnot and MakeUniform that corner surface to simplify it somewhat.

MatchSrf the edge that looks funny for tangency

Then MatchSrf the outer edge as well:

(Note! different settings)

Then join and I think it looks OK
