Trying to join two batwing surfaces

I’m trying to join to batwing surfaces converted to subds but I cannot figure out the points(vertices) where they should join. I want to join both of them so as to create one compound batwing minimal surface.

Both of the surfaces have the exact orientation.

The file is in Rhino 7 format.

Please help.

bridge or stitch will be the commands you will want to use, the only question is do you want to add faces between the objects or do you want to just knit them together.

if you want to add faces, use bridge.

if you want to knit them I’d use stitch and go one point at a time-
