Revit schedule calculated value

[wwydock]

i have my revit schedule for mysheet list. its grouped by my SHEET DISCIPLINE parameter and then ordered by sheet number. I want to create a calculated value that uses an if/then formula to apply a numeric value based on the discipline name. I keep getting the error message "Improper use of boolean expressions". I have checked the help menu and I have not seen anything that says i can not perform this kind of function. Ultimately this should be a group if formula inside if formulas to cover each of the disciplines. I have the Discipline for the formula set to common and the type set to number. Below is the formula i am trying to start with.

if(SHEET DISCIPLINE="ELECTRICAL",3,0)

Thanks

Currently, Revit does not support the use of Text in conditional statements. This is one of the major limitations to Revit's formulaic capabilities, along with not supporting the combining or joining of Text strings. You will only be able to perform this in the opposite direct, meaning that the SHEET DISCIPLINE text value would have to be driven by the Integer Parameter.

In the meantime, assuming you are using your own parameter to define the discipline for this, because the built-in discipline parameter is a fixed list which doesn't include Civil or General for example, you could place a number as a prefix to the discipline. Then you can sort the schedule using the parameter by letting the criteria focus on the number portion instead of the text of the discipline. This allows you to use a logical number sequence but also let users read something meaningful without worrying about sequence, it could look like this:

01 General

02 Civil

03 Landscape

04 Structural

05 Architectural

06 Interiors

07 Mechanical

08 Electrical

09 Plumbing

10 Fire Protection

If you associate view types with view templates then users won't need to even assign the value, for the majority of views at least.
