Import Cad files at runtime : No mesh in 3D view (but are in the outliner)

We try to import Cad files using Datasmith at runtime.
Currently, I test with DWG files. (But it seems the same with other CAD format)

When using a Widget Editor utility blueprint, the script works well. (But it’s not runtime :wink: )
Using the same script within an ACTOR utility blueprint nearly works but the objects don’t appear in 3D view.

=> They are created in the content browser
=> They are in the outliner
=> But we don’t see them in 3D view.

We try to add delay, to modify Datasmith import options and many things.

A possibility could be to choose ‘Asset only’ in datasmith import base options but we don’t success to spawn the asset after importation. (If you know, I take)
=> Spawn actor from class / Datasmith Scene Actor => but after ???

An idea or workaround for runtime importation or spawn datasmith actor ?
