Using Associative Hatch
You can set an option to specify whether hatch objects created by property
alteration queries and thematic mapping are associative.
NOTE This option affects drawing objects only.
Hatch patterns used in thematic maps.
Associative hatch maintains a link between a hatch object and its boundary:
if the boundary is modified, the hatch updates automatically. However, if the
boundary if modified so that it no longer encloses the hatch or if any of the
boundary objects are deleted, the association between the hatch and the
boundary is lost.
When querying multiple files, it is easy to lose the association between a hatch
object and its boundary. If you want associative hatch, the easiest solution
may be to delete the old hatch object and recreate the associative hatch after
you finish modifying the attached drawings.
To maintain an existing association, keep in mind these points:
If you modify an object that is part of a hatch boundary, be sure that your
changes do not break the boundary. That is, you can enlarge a circle, but
do not trim it. You can extend the corner of a square, but do not open it
up.
To save a new associative hatch object to an attached drawing, all the
boundary objects must be in the same attached drawing. In addition, all
objects must be saved to the attached drawing at the same time. If any of
the boundary objects are saved to a different file or are saved at a different
time, the association is lost.
