Creating a Drawing Index

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.

NOTE Whenever 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 Application 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 you specify.

■ 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 specify.

■ 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 The status "Out-of-Date" means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 An index could become out-of-date if you modify objects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.
