From Rhino to VW 2017 - Solid volume in Architecture Posted February 2, 2018 6 minutes ago, Kevin McAllister said: Yes. Use the Join command to create a Closed Polysurface. However if its too complex it may still come into VW as surfaces instead of a solid. Kevin Thanks Kevin. I hope it doesnt, the aim is to be able to section through it and see it as a solid volume. Not sure if the picture I joined is too complex or not. I'll try and let you know. Have a nice weekend.
