Merge surface question

Rhino
1

Is there a way to “combine” in some way all 3 surfaces in this file into a single untrimmed surface? Either as a single span surface or as a multi-span surface?

Or, is there a way to create the merged shape as a single surface (either single or multiple spans)? A key feature is that the result is an untrimmed surface so that the boundary CVs are located at the boundary edge and continuity is maintained at the span junctions.

Or is the only available approach limited to joining the surfaces into a polysurface and thus be forced to continually match surfaces as the individual surface CVs are adjusted?

No, NURBS are rectangular, that’s not.

It looks like this is symmetric so it could be split up that way and continuity can be maintained easily, or work with it as a single larger trimmed surface.
