Please change Function on walls to be and instance parameter that only contains Exterior or Interior. Then Autodesk could add another parameter, also instance to indicate usage: Foundation, Core-shaft ect.
Next we are in need of an instance parameter to Fire rating, not was the wall can, but the demands to the wall.
Fire Rate demand.
Last but not least, we need a parameter (Instance) to indicate if the wall are Stabilizing
NEW parameters:
Stabilizing = Instance Yes/No
Fire Rate Demand = Instance Text
Usage = Instance Drop down
Changed parameters:
Function = Instance instead of Type
