eta/DYNAFORM provides
two methods to create the addendum. If checkbox
of the By Segment option is toggled on, the user can create the addendum
by multiple segments using different master profiles. If the checkbox is toggled
off, the entire addendum will be
created based on a single master profile.
After selecting a
master profile, the user clicks on the Assign
button to display the dialog box as illustrated in Figure 7.3.13.

the By Segment is toggled off, the Select Region button is disabled. The user clicks
on the Apply button to create addendum around the entire outer boundary. Figure
