Datasmith - Selected Metadata Not Exported (Revit 2024.2)

[ryan.lenihan]

In Revit 2024.2 with the Autodesk managed version of the Datasmith exporter, we're not getting the metadata correctly exporting. We are only getting Category, Family and Type, ie:

<MetaData name="1be9e9a50f9e4b8cb228a59d16f2d93c_DATA" reference="Actor.1be9e9a50f9e4b8cb228a59d16f2d93c">
<KeyValueProperty name="Element*Category" type="String" val="Stairs"/>
<KeyValueProperty name="Element*Family" type="String" val="Assembled Stair"/>
<KeyValueProperty name="Element*Type" type="String" val="Stairs 1"/>
</MetaData>

I've double-checked the export configuration, but I can only select the parameter groups, not the individual parameters like we could in previous versions of the exporter:

Is there something obvious that I'm missing or that I need to check, or is this a bug/limitation of the current Datasmith exporter?

Did you find something about that?
I´m starting a new defaut template and ctrl C CtrlV from my 3D Model and the exrpoting includes all metadatas. So, I don´t know whya, but maybe it´s some bug from another old versions...

At the time I ended up using RTV Xporter, as it's version of the datasmith exporter provided all metadata. It was either all (in RTV) or nothing (in the adsk exporter).

I then wrote a c# application to post process the datasmith files to remove the unrequired metadata.

I haven't checked in the latest patches, but I do see some changes have been made. I have another project coming where I need to export to unreal, so I'll find out all about it soon.

Hi,
I have the same Problem with the Datasmith-Export.
I tried with Revit 2024.3 + Twinmotion 2023.2.3 and with Revit 2025.4 + Twinmotion 2024.1.2.

I also tried with a new default template + Copy/Paste.
Do you have another solution to export all the Metadata in the Datasmith-file?
