In V19 when I try to copy the shadows from a 3D window (vectorial engine) using the marquee tool, I get the following message: "Warning Not Enough Scrap-Memory for Copy!"
V19 is otherwise running well, so I don't think it is a RAM issue. And I get the message if I only select a small area of shadows or large.
I have also tried turning on and off background processing, and restarting both the computer and archicad, none of which have helped.
I have used this feature quite a lot in previous versions and it has never been a problem.
