If you need more help with this question be sure to ask in the Solidworks group here on GrabCAD.

You can import an image of the desired curve, and simply trace over it.
Or a tool like Vector Magic, or Auto Trace can be used to transform a raster image into a vector format.

You could also import a series of point coordinates, then generate a curve through the points.
