    As far as I have looked into this the redraw is generated by FastCAD. You will see the same kind of redraw when placing the first copy with the PART command.

      As far as I have looked into this the redraw is generated by FastCAD. You
      will see the same kind of redraw when placing the first copy with the PART
      command. Just after placing the first copy with PART the whole drawing will
      redraw. It will not redraw if you place more copies in the same command.
