Table Of Contents
When information in the data source has changed that affects the extracted
data in a table, you are notified the data is not current. (Notification does not
occur with attribute extraction tables.) Depending on how the DXEVAL system
variable is set, the Data Extraction - Outdated Table dialog box displays when
certain commands are used, such as OPEN or SAVE. By default, DXEVAL is
set to check if the extracted data is not current without automatically updating
it when the PLOTor ETRANSMIT commands are used.
IMPORTANT When DXEVAL = 8 (update on publish) and BACKGROUNDPLOT is
set to 2 or 3, then you will be prompted to update when publishing the files.
However, the tables in the DWF file will not be updated. To include table updates
in the published files, set BACKGROUNDPLOT to 0 or 1.
You can set auto-updating to occur with these commands: SAVE, PLOT,
PUBLISH, or ETRANSMIT. When auto-updating is enabled, the extracted data
is automatically checked to see if it is current with the data source. If not, the
update process occurs without user intervention. With PLOT or ETRANSMIT,
the data extraction is updated prior to the plotting or electronically
transmitting the drawings, which are not saved.
When you open multiple drawings at the same time, and the DXEVAL setting
in each drawing is 1 (to check for updates as the drawing is open), a dialog
box displays for each drawing that contains a data extraction table that is not
current. You can choose to update the drawing or to skip all updates.
You can run the update later from the shortcut menu for the data extraction
table.
If the cells in a data extraction table are edited in a previous release of the
program, and then opened in the current version, the table cells that were
edited are unlocked. When the table is updated in the current release, a dialog
box displays indicating some cells were overwritten. You can choose to
overwrite the cells or skip the cells during the update.
NOTE It is recommended you turn on notification before doing a final save, plot,
publish, electronic transmittal, or archive.
