Hi Alan, sorry no MoI does not currently have a match surface tool like that. If you need that right now it would be good to use Rhino in combination with MoI and do that particular task in Rhino.

But if you are constructing surface 1 out of some curves usually it is best to construct a single larger surface instead of half and then there is no need for any additional matching.

See here for some examples:

As a remedy you can cut the center portion out from both surfaces and use Blend....

Thanks Michael and Burrman.
