I would like tocopythis part and or drawing as the new part number, make afewdimensional changes and have my new drawing/part. I have doneacopy and paste in windows explorer and change thedrawing/partnumber, but this does not work right. It still has oldnumbers inproperty manger of drawing. Can you help?
