Why is Revit MEP making my bends grey, it seems to be a bit random, and there is no filters or visibility issues that I can find.
Found the glitch.
It was to do with underlay. The levels on this job are weird. Mezz is at 3.3m which is actually within the ground floor zone as well.
Ive set underlay to none, and the bends all fixed them selves.
