Table Of Contents
If you no longer want to update a field, you can preserve the value that is
currently displayed by converting the field to text.
The field expression, consisting of escape characters and a field code, is shown
in the Insert Field dialog box but cannot be edited.
Update Fields
When a field is updated, it displays the latest value. You can update fields
individually or update all fields in one or more selected text objects.
You can also set fields to be updated automatically when the drawing is
opened, saved, printed, and regenerated.
FIELDEVAL controls whether fields are updated automatically or on demand.
The Date field cannot be updated automatically regardless of the setting of
FIELDEVAL.
NOTE When the DEMANDLOAD system variable is set to 2, fields cannot be
updated until you use FIELD or UPDATEFIELD.
Contextual Fields in Blocks and Xrefs
Some fields are contextual; that is, their value is different depending on which
space or layout they reside in. For example, because each layout can have a
different page setup attached, the value displayed by the PlotOrientation field
can be different in different layouts in the same drawing.
