Whenever you open a drawing that includes database links, AutoCAD Map 3D toolset 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 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 toolset targets just the regions included in the Location query.
- Property index — Organizes object properties. AutoCAD Map 3D toolset targets only the objects with the properties you specify.
- SQLLinks index — Organizes the link templates and key fields of the drawing. AutoCAD Map 3D toolset 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 toolset.
- Object Data index — Organizes object data. AutoCAD Map 3D toolset 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 The status "Out-of-Date" means that the object data index on that field is not consistent with the attached object data. An index could become out-of-date if you modify objects without first loading AutoCAD Map 3D toolset.
