Can somebody convert a .DXF file to a 3D Model which I can import in Solidworks?

Hey everybody,
I am Michael and I live in Germany. Its my first post in this forum. I have a DXF file of a cylinder of a radial engine. I need the 3d model of this part, and I know how to convert DXF to 3d generally. But with this drawing, which is pretty complicated, it doesnt works.
Would be great if somebody could help me!
