To reduce the amount
of time it takes to perform a drawing query, create an index. Instead
of searching all location, property, object data, or database links
to find matching data, AutoCAD Map 3D searches only the relevant index.
you open a drawing that includes database links, AutoCAD Map 3D automatically
creates a database link index and keeps it in memory. To save this
database index to the drawing, select the Store Links Index In
Drawing File option. To set this option, select AutoCAD
Options from the Setup menu.
Select the System tab. This feature is
especially useful when you edit your attached drawings directly.
You can create the following
kinds of index:
- Location index — Divides drawings
into regions. AutoCAD Map 3D targets just the regions included in the Location query.
- Property index — Organizes object
properties. AutoCAD Map 3D targets only the objects with the properties
- SQLLinks index — Organizes the
link templates and key fields of the drawing. AutoCAD Map 3D targets
only the objects with the link templates and key field values you
- EED index — Organizes
Extended Entity Data (EED) attached to objects in drawings
created in AutoCAD Data Extension (ADE) 1.0. You cannot create EED
in the current release of AutoCAD Map 3D.
- Object Data index — Organizes
object data. AutoCAD Map 3D targets only the objects with the object
data you specify. After you generate an object data index, a status
message appears beside each indexed field name. The status "Current"
means that the object data index on that field is valid and consistent
with the attached object data. The status "Out-of-Date" means that
the object data index on that field is not consistent with the attached
object data. An index could become out-of-date if you modify objects
without first loading AutoCAD Map 3D.
