I try to cut a complex polysurface with a closed curve.
Trim can’t cut.
It seems to work if I use the _Split. New edges are formed but the polysurface is still a closed solid.
But at the same time, I see the result on the command line: One polysurface split into 2 pieces.
How to make these two pieces separate, without using the _Explode and delete excess surfaces in manual?
