Elements without GUID after IFC export

Hello,

 

When exporting to IFC, the IFC exporter creates GUID's for all elements in the IFC. The GUID is also stored in the Revit model in a read-only parameter when the checkbox "store the IFC GUID in an element parameter after export" is checked. This works fine up to this point.

Only when an element with this read-only parameter is copied, the GUID will be emptied out, wich seems the right thing to do since the GUID has to be unique and duplicate GUID's must be avoided. When i now make an IFC export the element will get the GUID assigned to it in the IFC file only it will not get assigned in the Revit file (it probably can't write to that parameter since it is made read-only). This forms a big problem when trying to identify elements by their GUID. 

 

Is this problem known by you and can this be solved so that all elements in Revit will have the same GUID as those same elements have in the IFC export?

 

I will be happy to hear from you.

I am not aware of this issue. I probably would try to solve it by using Dynamo.

With dynamo you should be able to read the GUID of the elements and then store it into a (new) parameter.

(I expect that the IFC exporter does something similar)

Please mention Revit version, especially when uploading Revit files.
