The coordinate data dimension system is defined during a FeatureCAM programming session. The Inch or Metric dimension system is saved as a 'flag' in the CNC data file.
When Post is executed, it compares the input dimension system that was saved in the part program with the output dimension system that was selected in XBUILD (CNC-Info > General Information dialog). If they differ, a conversion factor is automatically applied. Therefore, a CNC data file that was created in XBUILD must be built in accordance with the required output dimension system.
