    Quantity Takeoffs for Walls & Associated

    Out of the box, it appears you can't find gross wall area, nor can you differentiate between exterior walls and interior walls for purposes of finding LF of floor base. In perusing the internet, I couldn't find solutions...

    To what exactly?

    There's been (many) chats on the subject here for sure.


    Fundamentally, the "issue" is that walls are their linear, analytical, length-at-centre, and you need to do bad-maths to consider their thicknesses.


    As for differentiating between exterior and interior? Well with their function parameter property correctly populated, there's no issue there.

    Hi SnowyWeston,

    I'm not worried about wall centerlines or thicknesses. But typical contractor estimates take the walls as gross SF and Revit yields net SF. I tried to figure out how to do calculated schedule columns with no luck.

    Regarding the Wall Base, I tried the same thing in order to put a different LF formula column for interior walls (which have Wall Base on each side) and exterior walls (which have Wall Base on one side only). I was hoping to be able to do an IF function with the Family Type, but it wouldn't let me.

    Perhaps these things are possible if I had a better handle on Shared Parameters. But since what I am seeking is such a common thing in construction estimating, I was surprised the solution wasn't obviously available.

    Thx,
    Geof Narlee
