ALL 3D VIEWS ON SHEETS GONE BLACK

[Ugljesa Janjic]

All of a sudden, all of my 3d views placed on sheets turned black. They look just fine in their original views, but on sheets they are just big black rectangles. What is happening here? Does anyone know how to fix this?
KIND OF URGENT. THANKS.

Check that the pen set applied to the view on the sheet is the same as that applied to the saved view.

Thanks for your reply. After checking everything, including your suggestion, and then realizing this is an issue on ALL of my projects, I decided to RESTART the ArchiCAD and, believe it or not, it worked!
Stupid me, should have thought of that before. Sorry about the bother and thanks again.
