Does anyone know if there is an easy way to fix this kind of edge/seam in a surface?
Split out the offending part and make some section curves through the cut-out in two orthogonal directions. Then use the edges of the opening with the created section curves in NetworkSrf to create a G2-continuous patch.
Thanks, I was able to get it by splitting the curves and using blend-curve on the ‘broken’ part.
MatchSrf would be the tool to use, but the surface to be changed must be untrimmed along that edge. You’ll need to replace the edge fillets as well. Post or send me the object and I’ll take a look.
