Hello
I do it that way in these cases:
1. Assigning as PredefinedType attribute: USERDEFINED
2. Filling the ObjectType as your own custom type: "RAISED ACCESS FLOOR"
I think it's the aimed and right use of the Userdefined option on PredefinedType attribute field, using de OBJECTTYPE description.
Check with IFC File Analyzer (NIST) your IFC and generate the Spreadsheet, and you'll can see the results.
