Use this procedure to update a field manually.
By default fields are updated automatically when the drawing is opened, saved, plotted, regenerated, or sent via e-transmit.
If you have changed that default, or want to update a field without performing any of the operations listed above, you can do so by updating the field manually.
Fields can be contained in AutoCAD text, multiline text (mtext), table cells, attributes, property set definitions, object properties, object styles., and project details.
