Cannot export the active 3D view in Revit to Unreal using Datasmith?

Hello, I receive the following error while attempting to use the Datasmith Add-in and export to Unreal.

I haven’t had this issue with any other Revit models. Has anyone else run into this issue? I’m hoping to resolve this as I continue to compare my settings to previous Revit projects.

I’ve attached my 3D View Settings from Revit. From what I can tell everything is the same as the last working project.



I had the error a week ago. I had no idea a new release came out and fixed the issue. Thank you!

Hi April.

This is a known issue visible here: Unreal Engine Issues and Bug Tracker (UE-66985) and that should be fixed in one of our recent Datasmith hotfixes.

Please make sure to update to the latest Datasmith version for the UE 4.21 release. This includes updating both the Datasmith importer plugin in UE4 (via the Epic Games launcher), and the Datasmith exporter plugin in Revit (available here: Datasmith - Unreal Engine)

I hope this helps.

For all future Unreal Studio/Datasmith issues or questions, please be sure to log your issue to our dedicated Unreal Studio support site -

Thank you.
