# Assign global object parameter values

Global object parameters are assigned to reference objects in graphic displays.

Use the Global Object Parameter Values dialog box to assign unique parameter values to multiple reference objects without having to break the links to the base object's tags and expressions.

## To assign global object parameter values

1. Select a reference object on a graphic display.
2. Right-click and then select Global Object Parameter Values from the context menu to open the Global Object Parameter Values dialog box.

   or

   From the Edit menu, select Global Object Parameter Values.

3. Assign values to each of the parameters defined in the Global Object Parameter Definitions dialog box.

   The Global Object Parameter Values menu choice will be unavailable if:

   - the object selected is not a reference object
   - the object selected is a reference object but its base object has no global object parameters defined
   - the object selected is part of a group reference object

## Options

- Name

  Names of global object parameters defined in the Global Object Parameter Definitions dialog box are shown here. Users cannot edit this cell.

- Value

  Type a value for the global object parameter. This can be any string. If a tag is selected in the next cell, the tag will be displayed in the Value cell. This property is optional.

- Tag

  Click the Browse button to open the Tag Browser and select a tag or a folder as the parameter value. Selecting a folder that contains a structure tag establishes a path to the structure tag that will act as the backing tag for this reference object.

- Description

  The description specified in the Global Object Parameter Definitions dialog box is shown here. Users cannot edit this cell.

  Tip: | To ensure that changes made to the tags and expressions in the base object are also made in the reference object, set the global object defaults in the reference object as follows: LinkAnimation = Link with expression LinkConnections = True
