I did some 3D models in Autocad and now I am trying to import them to Rhino, but a lot of the surfaces disappear, especially curved circular surfaces. Everything is a 3D solid.
These 2 messages appear:
- “An invalid polysurface was read. Would you like to salvage as much as possible of invalid polysurfaces?”
- “Invalid surfaces will be removed from polysurfaces and returned in separate polysurfaces with object name Bad Faces”
For example, it also happens to this this, the top surfaces not just disappear, but also other geometry is changed…
