Often, if you export from a 3D program like Solidworks you will sometimes get splines for no apparent reason. this can be improved by exporting section views.
Once you have a Spline, it cannot be exploded or edited into something useful (as far as I can tell). The only way that works for me is to draw lines/arc or polylines over the splines(on a different layer, so you can delete the splines). Usually not difficult as all the snaps etc work on a spline, and it can quickly be replaced if the geometry is valid (basic lines / arcs).
That will probably be true for most CAD software, but in some software you may be able to do a "remove arcs" or "remove lines" operation that will leave you with a polyline that is an approximation of the spline.
