I have had this new problem with Revit 2016 few times a week.
Suddenly ALL views and sheets become empty.
NOTHING but reopening the project makes model and graphics visible again.
Revit buttons work and I can syncronize and save.
I have ThinkPad laptop with two extra displays.
I have updated gpu driver (Nvidia M2200).
I have unchecked "Use Hardware Acceleration" from Revit Options.
Win10 updated.
What else could help?
