After triming a closed polysurface with another closed polysurface, I get one closed and one open polysurface. I would like to make a booleen union on them to have only one closed polysurface, but it fails due (I guess) to the open polysurface. Is there a way to get to this final closed polysurface? Perhaps if I could close this open polysurface, the booleen union will work, but how could I do this?
Thank you very much
