You can update a schedule table at any time by selecting it, and clicking . This updates the values in a schedule table when the automatic update option is turned off. Always update schedule tables before plotting the drawings that contain them.
When you update a table manually, the table is refreshed to reflect any changes to objects or to property set data attached to objects or object styles. Objects added to the drawing after creating the schedule table are not included in the table unless Add Objects Automatically is specified in the table properties. To ensure that the table contains accurate information, close and re-open your drawing before plotting schedule tables. Certain changes to drawings, such as reference editing, are reflected in schedule tables only when a drawing is reopened.
