DWG import just imports nothing - empty D

I wanted to test the datasmith import for CAD files, here DWG files from AutoCAD. Using UE 4.25.1
Having enabled the Datasmith Importer, Datasmith CAD Importer and Datasmith Content Plugins, the Datasmith Icon is present and allows me to select from a whole bunch of formats, including the DWG file format.
The files I have all do not work correctly, so going for an “official” one, downloaded from autodesk examples AutoCAD Sample Files | AutoCAD | Autodesk Knowledge Network - here the “Architectural Example (Imperial) (dwg - 145Kb)”

Chosing an import directory and leaving import options at default

What happens on import: Import starts, then the only thing that happens is, that my scene camera in the level gets reset to the scene 0,0,0 postion.

In my import folder, I find a DataSmith Scene object. Opening this just contains this:

No geometry, nothing in there…

I could not find any informations about how to import CAD files, except for C4D, for which an extra plugin exists. Also, lot of infos I found seem to indicate, that the DWG import is not on a high priority on the list of things to be done…

What do I do wrong with this?

Hi, did you ever find a solution for this issue?

Unreal Datasmith only imports 3D content. If your DWG contains 1 or 2D representations they are discarded.
