Irregular Results with Adjacent Faces

thanks @AbrahamYezioro, @Erikbeeren

wow - thats so peculiar? It definitely is not working for me. I wonder what the difference is?

I’m using Rhino 7.2.21021.7001 on Windows 10 Home edition - running on Parallels on my MacBook. I have double checked and the tolerance is set to 0.001m

Interestingly, if I change the tolerance setting in Rhino - no change occurs in the Grasshopper, model no matter what I set it to. If I set it to 0.1m or 0.01m or 0.0000001m I always get the same result (even after a GH ‘Recompute’):

BUT: if I set the Rhino doc tolerance to a different value (say: 0.01m), save the Rhino file and close everything, then reopen - now I do get a different result (the ‘Surface’ is no longer recognized on the ‘original’ but DOES get recognized o the copy now…) Again: not changing anything about the geom, just the tolerance setting, save, close and reopen:

If I do all that again: set Rhino tolerance to 0.1m, save, close, reopen, now I get yet another result - in that case both surfaces are recognized correctly?

again - nothing at all changes until I save and reopen the file in any of these cases, even when I ‘recompute’ the GH scene?

That seems odd, doesn’t it? Is there a certain tolerance it ‘should’ be set to for LBT to work best that you know of?

regardless, thanks so much for taking a look! Really appreciate it.
