An object data index speeds up drawing queries on drawings that contain object data. The index is automatically updated each time you save changes to a drawing. In this exercise, you create an object data index for the Redding.dwg drawing file.
To create an object data index
Select all the options on the left except EED.
Select a data table, then select its data fields.
The indexes are created. As you work with your drawings, repeat this procedure periodically to update and recreate the indexes.
You used Quick View and Preview queries to look at objects in attached drawings. You used Draw queries to add objects from attached drawings to the current drawing. You created an object data index to improve the performance of data queries.
To see the effect of the object index on performance, repeat Exercise 5: Query object data with the new index you created.
