Import dwg loses dimensions

I’m trying to import a dwg file (drawing) into sketchup and it works but I’m not getting any measurements. If I open the same file in a dwg viewer on my mobile (android) then I can see the measurements. So there is something going wrong when importing sketchup.
Very grateful for the help and your time.

There’s nothing going wrong when importing your .dwg file. Read this:

Dimensions are unsupported elements.

The SketchUp DWG importer only imports “geometry”, that is lines, faces, solids etc. Annotation objects are ignored.
If you import into LayOut the annotations are respected.
