IFC Export from Revit Model!

Good morning!

I would like to export an IFC model from an existing revit model.
I really want the areas of all the rooms to export correctly and be included in the ifc listings/schedules.

In revit I have created model groups for each room and added additional thin layers of interior finish walls (for floor, walls, ceilings - see attached picture). Each room also has its own room-tag with an area.

I have tried to export the IFC in various ways and I am running out of ideas. 
First I tried with IFC 2x3 and the IfcSpace settings for the rooms. Unfortunately it does not export all rooms. The same applies to room-tags - only some are visible.
Then I tried also with IFC 4 export and IfcRelSpaceBoundary settings for rooms. More rooms were exported, but still not all of them. Recently I also heard about IfcQuantityArea command, but I don't know to which version of export it refers and if it helps anything. I´ve exported the report generated in IFC File Analyzer and it showed me only the position with IfcQuantityArea - but I haven´t used this command while exporting IFC from Revit file.

Or should I set a new parameter on my own in the project like IfcExportAs for the area of every room?

Has anyone had similar experiences and would be able to help? I would be very grateful!

Do you have different phases in your project?

 

Even if you havent:

 

Try choosing the phase the rooms are assigned to within the IFC export tab as seen in the picture. 

 

You could also try to rename your schedules and put "IFC" within its name and check the box when exporting to only include schedules with IFC within their name.

 

 

These 2 steps usually helped me getting there. Maybe it will for you as well.
