Hi there, I am having trouble with the BlendSrf command. I am trying to join two trimmed surfaces. oahu small.3dm (2.9 MB) Thanks in advance for your help.

your surfaces are a mess. they are folding into each other while having stacked uv control points. try deleting a few rows till they straighten out and use match surface then join.
