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

Click Preview to get an idea of the result:

-
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.
