Yes, I may do the offset with your dxf, but I get the same error message as on my sketch, with the difference , that your sketch finishes with a resulting good offset ???

I will search for the errors in mine

The first thing I did to your .cdr was select it, and on the properties bar, I tuned line width to “hairline” then removed the color using the pallet.

Yes that’s exactly what I did too.  
No again :

- Separated all curves to be able to export only the outline.
- No Fill and Hairline
- all points selected , reduced points
- export only selected object to DXF
- add DXF in Shap3d  
Same thing as usual, no offset possible

It drives me crazy.

here is my cdr and the exported DXF:
