Tested on Rhino 8.8 (SR8).

The command FillMeshHole does not appear to work correctly as it did in Rhino 7 (SR37). On filling a hole in the corner of a cube (this is a simple test case), the patch generated overlaps faces around the edge of the hole.

The hole to patch:

As patched by Rhino 8 (not joined):

And joined gives the same result:

I could create a single face bridge and then fill the resulting two separate holes, but this should not be needed as in Rhino 7 the hole is correctly patched

I would appreciate it if this could be resolved.

Thanks,

thanks @A_Veale for posting,

I see that it depends on which edge is clicked, on some edges I get lucky, but on most it creates garbage.
