Populating property values from an IfcClassification?
Hello! So, I have an IFC 4x3 model that includes an IfcClassification. I'd need to copy the classification IDs (Identification/ItemReference values, and preferably Descriptions too) to a “regular” properties for software interoperability reasons. The Copy Property Values workflow propably works fine, but I can't seem to find what to write into the Copy from Property input in this case 😊
Quite frankly, I find working with IfcClassifications somewhat confusing. As an example, for the following line I'm interested in the three strings, mainly the first one ‘1241’:
IFCCLASSIFICATIONREFERENCE($,'1241','Ulkosein\X\E4 | US',#721056,'Rakennuksen ulkopinnassa oleva pystysuuntainen rakenne. IFC-k\X\E4\X\E4nn\X\F6s: IfcWall.EXTERNAL_WALL',$);
Other ways and tips are also welcome!

Hi,
The first one is Location but it's null, the second one (1241) should be Identification, so you can type the property key there: DC:CSI:IDENTIFICATION.
It should also work if you type Identification, but if it doesn’t, then we have a bug that I’ll report, and it will get fixed.
The property names that can be used in copying are also easier to see in the Simplebim UI if you double-click the shopping cart icon of the classification group and take a look at the properties.
From there, it’s also easy to copy the property name or the key that you can use in the Copy Property Values step.
Fantastic, thank you! Double clicking the classification references to open the properties panel was what I was missing, works great now.
"Identification" does not seem to work, but DC:CSI:IDENTIFICATION works without issue.
On a related side-note, the longer sting in the IFC file, “Rakennuksen ulkopinnassa…” doesn't seem to be exposed on the UI. I would have though this would be the Description, but I might just be confused. I can work with Identication and Name, just something I noticed.
Yeah, I could reproduce the same issue with generic model. I will report that to our dev team.
It should be the description. I'll check if I can reproduce that issue too with a generic model.
