Match average leaves gaps between surfaces

Is this normal behavior? I’ve never used average before.

Note how the preview shows the surfaces with no gap, yet after I press OK, everything jumps back to the previous state.

you may have history enabled and are fighting that?

Hello - try RebuildEdges or Untrim - fwiw, your file does not show this gap here - the edges are .002 apart before the match, 8.26e-07 after… with Automatic on the isocurve direction.

MatchSrf works for me. Looks like the command is not completing for you.
