Not all ifc element visible in online viewer

[Bramdf]

Please help me,

When im uploading an exported IFC into BIM360. Not all my elements are visible in the online BIM360/forge viewer.

We are export a revit model to IFC 2x3 coordination. When we view this IFC in a new Revit file, or in BIMcollabzoom (local installed) we see all the elements we need. When we are uploading to autodesk viewer or BIM360. Some of the elements are visible, but unfortunately not all of them.

Is there someone who can help us with this problem?

See screenshot_problem:
At the left of the screenshot, our BIMcollab IFC viewer, and at the right our BIM360 view.
