IFC file incomplete - how to check?

[Simon_Weel]

Revit 2019. IFC Exporter 5.0.0. Client made us aware a brick wall was missing in a IFC file. The wall in question was there in Revit - no problems. After some investigation, it turned out a Door family had something to do with it. This Door type was not hosted in the outer brick wall - the one missing in the IFC file - but in the insulation. Both walls are Joined, so the Door appears correct in the model. After re-hosting the door in the brick wall, the IFC file was correct.

But the another problem surfaced. When examined in Navisworks, the brick wall in question still seemed missing?? When checked with BIMcollab ZOOM, we could establish the brick wall was indeed there. So was this coincidence?

This is a bit scary. Like why isn't the brick wall exported with a Door hosted in the insulation wall? It shouldn't make any difference which wall hosts a door, IMO. BTW - I think Doors and Windows should always be hosted in the outer layer of a wall, but that's another discussion.

As far as I know, the IFC Exporter doesn't post warnings if it finds a problem creating the IFC file. What I would like to know is how to check the IFC file? Like is every element there? Any ideas?

IFC struggles with phase filters. Set your views to show complete to see if that helps. Otherwise, i have no idea.

You have a setting to write the IFC GUID back into a parameter of your Revit model. Then you could create a schedule to see if all elements have a IFC GUID attached.

If this does not work you could possibly create a Dynamo script. Link the created IFC into the Revit project. Read Revit IDs from the Revit elements and the Revit ID from the linked IFC. Then verify if there is a mismatch between the two lists.
