This has been posted by others but from I can see there was no resolution.
Issue: Pre form “printability” shows that the proposed print setup is good. However, if you close the file and open up again, it will show red and the “printability” will show the “!” sign. But, if you make any changes and hit the printability again, the red will go away. So, I now need to keep closing and re-opening the part files to see if red shows up.
Why is this happening? The printability checking feature is not working correctly.
I am running 2.11.1
