Modifying Constraints

Editing Constraints

You can edit constraints by:

  • double-clicking on desired constraints
    or by
  • selecting desired constraints and use the XXX.N.object > Definition... contextual command.

...and modify related data in the Constraint Definition dialog box that displays.

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 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 menu item. Deactivated constraints appear preceded by red parentheses ( )  in the specification tree.

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 Symbols. 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 Display: the constraint (or parameter) name and value are displayed as well as the possible formula defined for this constraint.

Permanent Display

It is possible to permanently display the parameters of Part Design features as well as the valued constraints of Sketcher elements by using the XXX.object >Edit Parameters contextual command.

Provided that the Parameters of features and constraints option has been previously checked in the Options dialog box, (for more information see Display), the following dialog box appears:

If you validate the option, parameters or constraints attached to the selected feature are permanently displayed in the 3D area.

Colors

To change the color of a given constraint, either you use the Properties contextual menu item or the Edit > Properties > Graphic (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, refer to Infrastructure User's Guide).

If you wish to change the color for a given status, use Tools > Options. For more, see the Infrastructure User's Guide.
