You could use solidworks to trace the part if it can import an image to trace or use inkscape as I described and then import the DXF into solidworks. I've used solidworks in the past and it's a great program but it does take a bit of getting used to. No experience of solidcam I'm afraid.

Alternatively you could measure it carefully and create the sketch in solidworks from the measurements.

If I remember correctly, you'll need to create a sketch of the outline and then extrude that to the thickness of the plate. You then create sketches on the face of that part to define the holes / pockets / counterbores and create extruded cuts from those sketches. I'm not sure how solidcam works but in cambam you would then use the outline to create a profile machining operation (MOP) and then the other shapes to create pocket or drill MOPs.
