Managing Dimensional Constraint Parameters

Use the Parameters command to display the Parameters Manager palette to view and modify Dimensional Constraints parameters.

You can define, modify, rename, and delete constraint expressions and variables.

The Parameters Manager lists:

• Names of the Dimensional Constraints,
• Expressions, in which you can use:
  • Values
  • User-defined variables, and variables that represent existing Dimensional Constraints
  • Mathematical operators, functions, and constants
• Values that result from the expression

The list is grouped into Dimensional Constraints defined in the graphics area, and User-defined variables.

For detailed information about using expressions and variables, see Defining Dimensional Constraints Parameters.

To display the Parameters Manager palette:

• Click Constraints > Parameters Manager (or type Parameters).

To create user-defined variables:

1. On the Parameters Manager palette, click New user parameter .
2. Under User-defined, a new entry appears.
2. If necessary, in Name, edit the variable name.
3. In Expression, type a value or an expression.

• The value that results from the expression displays In Value.

To delete Dimensional Constraints or user variables:

1. On the Parameters Manager list, click a Dimensional Constraint or a user-defined variable.
2. Click Delete user parameter .
3. If the variable is referenced by a Dimensional Constraint in the drawing or in an expression, you are prompted to confirm deletion.

To change names of Dimensional Constraints or user variables:

1. In the Parameters Manager list, click a Dimensional Constraint or a user-defined variable.
2. Edit the name.
3. Press Enter or click elsewhere.

To edit expressions of a Dimensional Constraints or user variables:

1. In the Parameters Manager list, select a Dimensional Constraint expression or a user-defined variable expression and then click.
2. Edit the expression with operators, functions, variables and values.
3. Use the shortcut menu to insert a function: Right-click, click Functions, then select a function.
3. Press Enter or click elsewhere.

To filter the Parameters Manager list:

1. On the Parameters Manager palette, expand Filter.
2. Select an option to control the display of user-defined variables in the list:
   • All: Displays all user-defined variables.
   • Used in expressions: Displays only the user-defined variables used in expressions.
   • Unused in expressions: Displays only the user-defined variables not used in expressions. Right-click, then click Delete Parameter to remove unused variables from the list.

To sort the Parameters Manager list:

• In the Parameters Manager list, click a column name in the title bar (Name, Expression, or Value) to sort the list alphabetically according to the column title.
• Click the same column title again to restore the previous order.
