I like to turn the three overlapping trimmed surfaces into one single trimmed surface.

  1. The 3 trimmed surfaces are already there.
  2. I tried Region Union but it eats all the holes inside.
  3. Tried Brep Join, not work.

The right side of the trimmed surface is done by curve boolean in Rhino.
The .gh file attached here is simplified, not heavy.
Thanks!

There seem to be a couple of ways to do this.

Hello,

Your curves aren’t internalized.

The solution would probably be to extrude those surfaces, Solid Union them and take the interection with XY plane.
