here a simplified example - all surfaces was a single surface. Later during a project I wished that there is no split between the blue and red surface. I ask me, is there a simple way to remove the split between both surfaces? If not, maybe it’s something for the wish list - removing splits from an original single surface.
If you haven’t used ShrinkTrimmedSrf on those surfaces, untrimming either one of them will return the original surface. But you’ll have to cut out the door opening again so you’d want to use the KeepTrimObjects option.

This is the way I was gone in the past too. So, maybe we could it add as a wish. I imagine a workflow like:
the user start a command like _unsplit
the user select a split edge and Rhino automatic find all duplicated “original” surface parts and highlight all potential split edges which could be removed
the user select all split edges he want to remove
enter and done
We have _untrim and _unsplit could be an equivalent command.
Hi Micha - I am not sure I follow - are you referring to past split or trim operations, or just edges as they are now? Untrim handles the latter- you can pick any edges to untrim, they are not highlighted is the only difference; there is nothing, currently, recording the operations on an object, and nothing that I know of planned in that regard.
@pascal At my example above I would like to remove the trims between the blue and the red surface so that they are one surface, but all other trims are kept.
Yes, I see - MergeFaces on arbitrary shapes with the exact same underlying surface - famous last words, but somehow I do not think this can be all that hard to do.
I think I misunderstood the initial @Micha 's question, but I am curious about xMergeFace.
In the provided file, the degree of the original untrimmed Srf was U3 V1.
How is managed the GO at the split when removed with xMergeFace, does the resulting surface correspond to the structure of the original untrimmed surface or si there something averaged at that location ?
What do you mean by “GO”? G0? The underlying surface’s knot multiplicities are 3,1,3 x 1,1, so it has no kinks.
The faces are mergeable with the script because their underlying surfaces are identical. If you join the faces then _ShrinkTrimmedSrf the polysurface, the script can not merge the faces.
