Q: Is there a shared parameter I can use to write Revit formulas, such as if(), based upon a panel’s main disconnect type?
A: The DMEN_Panel_MainDisconnectType shared parameter returns a numeric value, which can be used in Revit formulas, based upon the main disconnect type:
- MLO/Main lugs only = 0
- MCB/Breaker = 1
- FS/Fused switch = 2
Example: Some engineers prefer that their panel schedules list the size of a breaker or fused switch main disconnect, or the bus size if the panel is main lugs only. To do this, follow these steps while editing the panel schedule template:
- Select where you want the value to appear on the schedule and run the Revit Calculated Value command. A dialog box will open.
- Enter the following values (enter anything for the Name field):
- Discipline: Common
- Type: Text
- Formula: if(DMEN_Panel_MainDisconnectType = 0, DMET_Panel_BusAmps, DMET_Panel_MainDisconnectTripSize)
- Press the OK button to insert the formula on the schedule.
You can also create a shared parameter that uses the formula above, add the parameter to the panel family, and insert it on the panel schedule template.
