Depending on what X-Y centroid / CAD data you need, there are different SW I've used to do the job. If you need PCB gerber "artwork" (rounds, rectangles, lines, squares,...geometric figures), you can use GraphicCode GC-Place & such - load the gerber

For extracting centroid you can use GC-PLACE or CAM-CAD but for it you need to ask the ASC file from your customer.
