I’ve never had this problem before. So it is very strange to me. Maybe someone knows what’s going on?
Another interesting note is that “showing hidden lines” reveals all the missing geometry. It seems to only be making a 2d of only objects which exist in that exact plane.
Okay, this must be well documented (even if i couldn’t find any exact info on it) because this problem only persists on Rhino8. saving as a Rhino7 file and launching it from there resolves the issue
