I am trying to design a PCB Badge. I did all my vector design in CAD and imported it as DXF.

First of all my issue is that closed poligons I specifically designed to be poligons in CAD load as separate segments.

OK, I can select them, but if I have an irregular design like the below shape, I select all segments and right click and convert to a solid region, it only creates this very small region and ignores the rest of the shape:

I also tried creating a shading in CAD, but that is not imported at all.

Do you have any solution how I can create such a complex solid regions from a DXF file? Do I need to convert them to be convex poligons?
