Modifying Constraints

Editing Constraints

You can edit constraints by:

double-clicking on desired constraints and modify related data in the Constraint Definition dialog box that displays.

selecting desired constraints and use the XXX.N.object -> Definition... contextual command...

...to display the Constraint Definition dialog box and modify related data.

About Diameter and Radius Constraints

You can obtain a radius constraint by editing a diameter constraint. You just need to double-click the diameter constraint and choose the radius option in the dialog box that displays.

If you need to create a formula remember that :

- the parameter corresponding to the radius or diameter constraint is referred to as "RadiusX.object"

- this parameter always contains the radius value.

For more about formulas, refer to CATIA-Knowledge Advisor User's Guide Version 5

Renaming Constraints

You can rename a constraint by selecting it and by using the XXX.N.object -> Rename parameter contextual command.... In the dialog box that appears, you just need to enter the name of your choice.

Deactivating or Activating Constraints

You can deactivate a constraint by selecting it and by using the XXX.N.object -> Deactivate contextual command. Deactivated constraints appear preceded by red parentheses ( ).

Conversely, to activate a constraint, use the Activate contextual command.

Changing Constraint Appearance

Display mode

When setting constraints, four display mode are available as explained in Customizing Constraint Appearance. Later, you can change display modes by selecting the constraint of interest and choose one of the following contextual commands

- 'Value Display': only the constraint (or parameter) value is displayed.

- 'Name Display': only the constraint (or parameter) name is displayed.

- 'Name/Value Display': the constraint (or parameter) name and value are both displayed.

- 'Name + Value (formula)': the constraint (or parameter) name and value are displayed as well as the possible formula defined for this constraint.


Colors

	To change the color of a given constraint, either you use the Properties contextual command or the Edit -> Properties -> Color (tab) command. You then just need to choose a color from the list (or you can define your own colors by selecting the More colors command at the bottom of the color list. To know more about defining personal colors, please refer CATIA Infrastructure User's Guide).

If you wish to change the color for a given status, use the Tools -> Options command. For more, see Customizing Constraint Appearance.
