Exporting an instance parameter to IFC

[robp]

We're using Revit 2019 and have 2 parameters for fire and acoustic ratings within our walls. The first is a type parameter which is the fire and acoustic rating that the wall type achieves according to the manufacturer. The second is an instance parameter which is the fire and acoustic rating a wall type is required to have in the instance that it's placed.

When we export to IFC the type parameter comes out no problem but the instance parameter doesnt.

We've tried using a custom property set as below but still no joy


#
#CustomPropertySets
#
PropertySet: Additional_Pset_Arch I IfcElement
Required Acoustic Rating Text
Required Fire Rating Text

Its easier to export custom parameters to your IFC model by just creating a schedule with IFC in the header: in your case, a wall schedule.

Thanks Alex I'll take a look.

I managed to sort it via the custom property set, i needed to change IfcElement to IfcWall. However doing a schedule sounds a lot easier route to go down.
