What post processing software are you using? You may want to check if the CL-Data file (*.ncl) that is output from Pro has CIRCLE statements in it. If it does not, then you will never output circles or arcs. If this is the case, you may need to check either your config options or the operation, setup, or sequence information.
If the cl-data file has the CIRCLE statements in it, then there should be a switch for outputting arcs instead of points.
