Whenever you change an alignment, PC-DMIS asks if it should update the commands below with the changed alignment. If you have this check box selected, and you click the NO button at this prompt, PC-DMIS changes the MACHINETOPART transformation if required. If deselected, the MACHINETOPART transformation does not change.
