PR: Federated Export with wrong IfcGuids

[denizmaral]

Problem Description

When I export a model with its link to same project or same IfcSite, IfcGuids are not correctly written in Ifc file. ExportIFCUtils give me actually correct guid but in the file it is something else...

Hmm, this may be by design. The GUID of a wall in a linked file inside a host is different than the GUID of that wall exported separately. Why? Well, Revit allows you to link in a file multiple times - the copies can't all have the same GUID. Or is this not what you are stating?

You are totally right. In that case I would love to see an overridden value, when I select a linked Element.

I think it should be like that: If I have only one instance of the link => take the Guid that is shown in UI
If there are more than one instances => override Guids in UI and take those.
It's not that common, that we have many instances of a link.
