Trouble viewing .dwg file in Fusion

[crdVD8A5]

Greetings

I have a .dwg file from a customer (Geometrien elementet.dwg, attached).
It is generated in AutoCAD (using hsbcad) and exported as .dwg. It consists of 3 layers.
View in AutoCAD:

I can also view it online at sharecad.org:

 But when it open it in Fusion, there are four elements, but they are all empty:

 
I also have the file as .dxf (Geometrien element.dxf, attached), but Fusion cannot/will not import it. 
It is critical that the file is accessible via Fusion. What can I do to open it correctly?

Best regards, 
Christian

ACAD_PROXY is not ACAD.

Use as reference in AutoCAD to create proper Autodesk ShapeManager 3DSOLID geometry.

Fortunately the geometry is simple.

Thank you for looking at it so quickly. A simple drawing exported from autocad was easily imported in fusion, so we suspected it had something to do with the type of lines used. The explode command solved the issue.
