Hello- I would DivideAlongCreases > SplitAttangtents=Yes the circular object and then get at the individual surfaces in the result from there.

Hi,

I do that and extendSrf 0.5, trim the result, repeat for arcing wall, do some more work on vertical wall, to marry to them, join all, everything looked ok, and I now have naked edges around fillet arc.

Command DivideAlongCreases explode then if I again join, is all ok, so extendSrf of the fillet edge has caused issues.
