Formula to calculate the area of the 2nd floor divided by the 1st floor

[Anonymous]

I was wondering if it's possible to create a formula in an area schedule that would allow the area of the 2nd floor be divided by the 1st floor.

For this type of operations, I suggest to export a schedule of floors from Revit to .txt. Then, open that file in Excel and add formulas that relate to the value of a cell.

Sure. Manually enter the Floor Area of Level 2 into a second Project Parameter Field Column in the Schedule and then create another Column which computes a value based on the Calculated Formula =Area/[the manually inputting value].

I was hoping to avoid manual input so that when the form moves the area adapts.

For a starter, add a Calculated Value parameter and choose Percentage instead of Formula.
