Hello all,

Since the upgrade to 2026x, we are experiencing issues with IFC export.

It seems that only the first instance of an object is displayed correctly, but every other instance of that same object is displayed as a wireframe.

The problem seems to occur for both IFC 2x3 and IFC4.

Several colleagues are supposed to send IFC exports to their clients today, to this is very urgent for us.

Is this a known issue, or should I create an SR for this?

Thanks in advance.

Below some imaging showing the problem.

On other projects we are experiencing the same issue.
