source drawings as the boundary. Using save back extents combines the extents
of all active source drawings as the boundary.
The edges of the boundary do not have to form a rectilinear shape. If you are
breaking using lines of latitude and longitude, the edges form a trapezoidal
shape.
Retaining Object Data
You can also choose to retain existing attached object data and links to external
database records on the objects created by the break.
Once the objects are broken, you can save the data back to the source drawings.

To break objects at a boundary
1 Open a drawing and attach the maps you want.
2 Define and execute a query to retrieve the objects to break.
3 Click Tools tab ➤ Map Edit panel ➤ Boundary Break.
4 In the Break Objects at Boundary dialog box (page 1666), under Boundaries,
choose how to specify the boundaries for breaking:
■ Use Save Back Extents Of Active Source Drawings — Uses the combined
extents of all active source drawings as the boundary.
■ Select Boundaries — Allows you to choose existing objects in the
current drawing. These objects need to form a closed area but do not
need to be single objects. Click Select and select the objects to use.
■ Define Boundary — Allows you to draw a single closed boundary on
