How to break a SubD model?

Such situation
There was a whole SubD model.
I removed several faces so that formed two separate pieces
But these two pieces remain interconnected.

_ExtractSrf or _Ungroup no gives result

How to break a model?

There’s no simple way right now, as far as I can tell, so here’s another workaround:

Control-Shift select one part.
_Copy (not _CopyToClipboard), chose the paste in place option.
_SelLast
_Lock
Control-shift select the same part again. Delete it.
_Unlock

Now you have two subD objects.

I don’t know why normal control-c copy doesn’t work with subobjects. It should be an option. ExtractSrf should also have a copy option.

And the delete that you did, in my opinion, should leave you with two separate SubD objects by default.

Well yeah, it’s nowhere near complete.

Does splitdisjoinedmesh work?

Tou can also extract meshfaces off an object and this will make a new joined mesh of the extracted faces. I presume this works on subd mesh objects too.

Just tried spliddisjoinedmesh and extractmeshfaces and extractmeshpart, none work.

Explode support for SubD objects is filed as RH-51988 for future reference. It is intended to look at creased edge loops to define regions to separate or to make disjoint SubDs separate.
