You can set an option
to specify whether hatch objects created by property alteration
queries and thematic mapping are associative.
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.
- When you add an associative hatch object
to the save set, all its boundary objects are added automatically.
If any of the boundary objects are locked, the hatch is not added
to the save set.
- When you remove an associative hatch
object from the save set, boundary objects are removed from the
save set automatically.
- When you add a boundary object to the
save set, hatch objects associated with that boundary are not added
to the save set automatically. To maintain the association, add
the hatch object to the save set.
- When combining solid hatch with text,
use the DRAWORDER command to make the text visible on top of the
