is there a way to convert a f3d file to step or igs

You'll need to open the file in Fusion 360 and export the file in the desired format.
This link suggests that Fusion 360 exports a wide number of file formats.
Iges, Step, parasolid, and acis can be imported by SolidWorks. I'd start with parasolid, then try step, acis, and iges if you run into trouble.
