|
This task consists in modifying the
mechanical properties and attributes of a
constraint. |
|
Open the AssemblyConstraint02.CATProduct
document and create an offset constraint. |
|
1. |
Right-click the offset constraint to
be modified. You can select the constraint in the specification tree or in the geometry. |
|
|
|
|
2. |
Select Properties from the
contextual menu. The Properties dialog box that appears displays four tabs. |
|
|
|
|
|
Constraint tab
The Constraint tab displays the name of
the constraint as well as the name and type of the supporting components.
You can rename the constraint if desired.
The
constraint status is also
indicated. In our scenario, the constraint is connected. To find out how to reconnect broken
or misconnected constraints, please refer to Reconnecting
Constraints.
|
|
3. |
Enter a new value in the Offset
field. For example, enter 75 mm. |
|
4. |
Set the Orientation option to Same
so as to reverse the blue component. |
|
|
Instead of using the
Properties contextual command to edit the properties as described
above, you can double-click the
constraint to be edited to display the related dialog box: in which you can
modify the same properties: |
|
|
|
Mechanical tab
|
|
5. |
Click the Mechanical tab. |
|
6. |
Three attributes characterize constraints:
| Deactivated: deactivated constraints are not taken into account when updating the
assembly |
| To update: the constraint does not reflect the latest changes to the assembly |
| Unresolved: the application detects problems |
|
|
7. |
Check Deactivated. The constraint
is modified accordingly.
|
|
|
|
Note that parentheses precede the constraint value, indicating that the constraint is
deactivated. These parentheses precede the name of the constraint in the specification tree
too. The color of the graphic symbol is modified. |
|
|
|
|
|
Feature Properties tab
|
|
8. |
Click the Feature Properties tab. |
|
|
This tab displays the constraint's
name as well as its creation and last modification date. You can edit the
constraint's name. |
|
|
Graphic tab
|
|
9. |
Click the Graphic tab. The Graphic tab lets you define the graphic properties of your
constraint.
| Color |
| Line type (Dotted, Small dotted etc.) |
| Thickness (Different values) |
|
|
|
Select the
color of your choice from the list. You can also define your own colors by
selecting the More Colors... command at the bottom of the list. To know
more about defining personal colors, please refer to CATIA
Infrastructure User's Guide. You cannot define a new color for deactivated constraints.
For the purposes of our scenario, you need to
reactivate the constraint. |
|
|
|
|
|
|
|
|
If you wish to change the color for a given
status (resolved, unresolved, over-contrained, invalid geometry) use
the Tools -> Options command. For more, see Customizing
Constraint Appearance. |
