I believe this is not a roof problem, but just another case of the even longer wished-for issue of ArchiCAD not displaying dashed (or any non-solid linetype) in a sensible way - so that two dashed lines on top of each other can result in a solid line.
Trying to reproduce this just now, I only had one valley that showed as solid. I dragged all of the roof planes away from one another, and all displayed properly as dashed.
My roof settings were for:
Show on Stories: all relevant stories
Floor Plan Display: Projected with Overhead
Show Projection: Entire Element
Uncut Lines: Solid Line
Overhead Lines: Dashed
and my Floor Plan Cut Plane was adjusted to include the entire roof.
Maybe I'm missing the problem though?
Thanks,
Karl
