It's pretty common process in the AEC industry to schedule materials, may it be paint or not, by room. To mention which room has which materials and for example how much (area) of each. Ideally, would be great to automate the floor/wall/ceiling finishes and mention areas of each, considering we don't always use box shaped rooms. Would be great if floors/walls/finishes/faces(paints)/ceilings/roofs could know in which rooms they have surfaces and what does surfaces use as materials, so we could have that in our material take-offs and room schedules automatically, avoiding hacks and tedious workflows.
While you're at it, please make the paints on the faces in the openings and inserts(walls and doors) thickness parts of the walls show up in schedules as well. This is very critical. I know a lot of people who avoid using Revit for inaccurate representation of materials, or impossible workflows. Thank you!
