The units for any model may be altered at any time. Changing the units does not affect the physical model size of an existing model, it only alters the reports and on-screen displays. It is important to note that when you create a new file and pick the units you are also selecting which set of defaults to use. Changing the units after the model is created does not affect which set of defaults the program uses.
