Use the list to choose one of the loaded project data (DST) files or click Load
Project to load a project data file that is not currently loaded in the Project
Manager.
Project Navigation Tree Displays a tree view of layouts or layout views in the
selected project data (DST) file, from which you can select an item for the
field.
Property Displays the properties available as fields for the item selected in
the Project Navigation tree.
NOTE If you recreate the field, because the layout is already in a project, you
should use a project property field, not a placeholder field.
Project fields (fields that were selected from the Project category) behave
differently than other types of fields. By default, other types of fields update
automatically when you save the drawing or when you use
REGEN (page 889).
In contrast, project fields store the last values that were used, and they display
these stored values if the information referenced by the project field is not
accessible. To update the value in a project field, use
UPDATEFIELD (page 1135)
command.
NOTE If the information referenced by a project field is not accessible, the value
for the field will be displayed as “####.”
Options for ProjectPlaceholder Fields
Type Displays a list of available placeholder fields.
Custom When Type is set to Custom, you can enter the name of a custom
property.
Options for Fields in the Objects Field Category
Named Object Type/Object Type When NamedObject is selected in Field
Names, lists the types of named objects in the drawing. When Object is
selected, displays the type of object selected. Use the Select Object button to
temporarily close the dialog box and select an object in the drawing.
Property/Name When NamedObject is selected in Field Names, lists the names
of all the objects in the drawing of the selected type. When Object is selected
in Field Names, lists the properties of the selected object that are available as
fields. When a block with attributes is selected, the attribute names are
displayed in the list of properties.
Formula

formula to insert in text or in a table cell.
