Hi john, I think you will need some advanced surfacing tools that MoI does not currently implement to do it in the way you're trying here, meaning by trying to directly generate surfaces to those outline curves. You could try the NetworkSrf or MatchSrf commands in Rhino for that type of surfacing approach. Another way that might be good is to try making a polygonal outline and use Max's sub-d smoothing plug-in.

For the case you posted I'd probably still try to build it as a single larger dome surface and then trim pieces of those out. You mentioned earlier about having some irregular cases that wouldn't work with that, it would probably help if you could post one of those too.

That would go something like this:
