Multiple Edge Bug

Something is causing this surf to have duplicate edges. Joining it to a neighboring surface makes weird edge loops. I think it might have something to do with MatchSrf.

Hello - I am checking it, thanks.

Yikes - was MatchSrf then Join what got it into this state?

History involved?


I didn’t notice it until the end of the model. The only active history involved was MatchSrf and I turned Lock=No to do the join. Could not find a way around it but to dupe the edges and build a new srf to replace.

The only prior history I can think of was OffsetSrf.

It was actually 2 MatchSrfs (tangent, nearest point, preserve iso) on that edge.
