I want to fillet some (holes).
There are so many edges that it is impossible to select them one by one.
add your definition
I want to put the fillet between the large square face and the hexagonal column.
I copied it exactly the same, but why is the side only round?
May I know what 81ms of your filledge component is?
something with your tree structure, i can not tell without script
what i can tell, is that if you want your join brep to work, in the most cases you have to flatten, not to graft the input…
Don’t graft the B input on the Join component!
