Edit Multi-Constraint

This task shows you how to quickly edit all or some dimensional constraints contained in a sketch.  

When you are editing a dimensional constraint value, the whole sketch is re-evaluated. Using the new Edit Multi-Constraint capability, the sketch behavior differs: the constraints values you modify are evaluated at the same time once you have click on OK in the dialog box.

Open the Constraint_DialBox.CATPart document, select the whole geometry using the trap tool and apply the Auto-Constraint command.
  1. Click Edit Multi-Constraint from the Constraint toolbar.
    The Edit Multi-Constraint dialog box that appears displays the whole dimensional constraints of the sketch.

In case you wish to restrict the selection, that is access not all of the constraints but just a few of them, first select the constraints of interest, then click Edit Multi-Constraint . Once the dialog box is displayed, you still can add other constraints if needed.

  1. Enter a new value, for instance 70 to edit Offset.21, the selected constraint.

  1. Select Radius.15 then enter 18 as its new value.
    Note that in the geometry area, Offset.21 is now displayed in light blue, indicating that its value is being edited. The new value is also displayed.
    Note that the dialog box displays initial values and current values.

  1. Click Preview to get an idea of the result:

 
  1. Assuming that you are not satisfied with the new value for Radius.15, just click the Restore Initial Value button.
    If you wish to restore several initial values, just use Ctrl while selecting the desired constraints, then click the Restore Initial Value button.

Diameter Dimensions

The Edit Multi-Constraint dialog box indicates diameter dimensions as radius dimensions with their corresponding values.

Contextual Commands

Standard contextual items, those you can get from any constraint definition dialog box, are available from the value field. These commands are:

  • Edit formula...: enables you to edit a formula.

  • Edit...: enables you to edit a parameter.

  • Add tolerance...: enables you to edit tolerances.

  • Change step: specifies an increment/decrement amount.

  • Add Multiple Values...: enables you to add multiple values for the object.

  • Add Range...: enables you to add a range.

  • Edit Comment...enables you to add a comment.

  • Lock: enables you to lock a parameter.
