This is my first post, although I’m a long-time Rhino user.
In my office, we use blocks quite a bit. For the first time today, I have a behavior that has never happened to me before. My typical working view settings have a single color for the backfaces, so I can make sure all the normals are correct. While I’m zooming around the model, everything looks fine. Then I edit a block, still fine. Then I finish editing the block and… the normals are all flipped! Edit the block again, the normals are correct, exit, and they are all flipped.
Anybody encountered this issue? Any help would be greatly appreciated.
