2.7.4 Sharing Classes Across Models
A class may be shared across multiple models by saving the class definition in its own file. We will
illustrate how to do that with the Channel class. First, look inside the Channel class, and then select
Save As from the File menu. The dialog that appears is shown in figure 2.42. The checkbox at the
right, labeled “Save submodel only” is by default unchecked, and if left unchecked, what will be saved
will be the entire model. In our case, we wish to save the Channel submodel only, so we must check the
box.
