Rhino’s “Surface match” tool lacks one very important setting and that’s the ability to match a surface edge with curvature continuity while preserving the control point flow. This usually means that the curvature matching is tiny bit bellow real G2, something like G1,97 I described it in detail in the following topic:
Many surface patches that look easy to build in Alias are nearly impossible to recreate in Rhino with a similar quality, or take too much time, because it still needs some extra functionality be added to become more powerful for surfacing.
