I was working with a Rhino6 model, and suddenly I cannot select any surfaces. I can select points and curves just fine. I’ve tried the Unlock command, and it says no objects are locked. When I go to the Edit menu and select all objects, points and curves are selected, but no surfaces. A left window drag picks points and curves but no surfaces.
If I bring up another file, I can select surfaces in it, and when I close the problem file and reopen it, the issue remains. So it is associated with that file somehow. Of course, I’ve also tried shutting down Rhino completely and reloading it - no joy.
Any ideas as to what is going on and how to fix it?
Edit: Here’s what an audit of the file shows - note no locked or hidden objects:
