Ideally when we want to find material take off for the stair tread area or riser what we do is we need to mutiply the tread depth*stair width *no of risers to get the tread area.
The figure what you acheive in revit is much more than the actual tread area...looks like it is calculating the tread surface area of each and every side of the tread including the tread thickness.
If you take a look at the image attached the tread area is much more then what you get after multiplying tread depth*stair width *no of risers.
Cud you please help me out in resolving this Issue.

Kind Regards,
Aliya

It is calculating all 4 sides... the same thing happens when you do a material takeoff of a glass panel with a thickness. Not what we want but logical in it's own way.

You could, I think, assign a default material to the treads and then use the paint bucket on the tops only in order to calculate the area you're after.

Hmmm I tried this recently in 9.1 and it didn't behave like that. I did it with a curtainwall and both types of schedules reported the exact same glazing area, so it didn't calculate each face separately. I'm not sure if what you're stating still applies. I'll have to re-test this and post an example.

It may not... I'm not speaking from experience here but from what I've read on the boards.
