You can control the fill level shown in your
objects.
To configure an object or group with
changing fill level:
Draw the object/group (or paste a
symbol). The properties tab dialog will automatically display,
unless you have turned off the Display properties
on new option in the Graphics Builder. (For a group, the
properties dialog will not display automatically; you need to
double-click the group.)
Click the Fill tab.
Click the Level tab (to the right of the dialog).
Enter a Level
expression (the expression that will change the fill level of
the object/group at runtime).
