Within a schedule formula I am attempting to generate a percentage or a ratio out of 2 areas. It seems that schedules aren't able to generate a number from 2 or more areas. Is this right?
For instance, I want to divide my hotel GFA against my total GFA to get a percentage.
If I type either 1 GFA as a number into the formula a get the correct percentage, but if I use both tagged areas in the formula I don't get a percentage or anything.
The obvious reason I would like to do this is so that I don't have to manually go into my formula's and update the specific areas once they have been redefined.
Are revit schedules not able to mixed units in formula's?
