Close Open Surface Rhino, Note the cutter’s Two methods for trimming a solid / closed polysurface resulting in a modified but still closed polysurface. I’m trying to make it closed surface and found tha tthe surface on the bottom is open. Could someone help me out? Don't do that, because a trim leaves the surface open, and then you're stuck. For cap, it says there are no closed planar loops of edges. Maybe there are options I’m missing within commands to make the result closed. To join surfaces that share an edge, use the Join command. Then run the Trim command to trim the bounding box surfaces that are extending past your model by using your 6.
