IGES file with points that lie on top of each other

Alright here is yet onother for the SW gurus. I have an IGES file with 2000+ points making up a cam profile, I want to use CURVE THROUGH REFERENCE POINTS and use a dragged pick box to select them problem is that every point has a duplicate point underneath it which causes a intesection error. Is there a way I can delete those duplicates with out individually picking them.

Thanks In advance for the help
