I have converted the metric DXF plates files to inches for those of us who would like to cut these plates but have existing machines and software setup to use inches. Also all the bolt and eccentric circles have been converted from polylines to true circles, this may help with some of the issues Robert Hummel noted about the polyline circles. If you have any problems just let me know..
Thanks
