To Redefine Component Constraint Sets
1. Select the desired component from the Model Tree or main window right-click choose 
from the shortcut menu . The Component Placement tab opens.
from the shortcut menu . The Component Placement tab opens.2. Select one of the constraints listed in the Navigation and Collection area of the Placement tab. For each constraint, you can redefine any of the following options:
◦ Constraint Type—Changes the constraint type to any reasonable type for the assembly.
 | You can only change the type for CoincidentDistance or Parallel. |
◦ Assembly Reference—Specifies a new assembly reference (for example, changes the surface on the assembly to which you are going to align the component).
◦ Component Reference—Specifies a new component reference for a placed component (for example, changes which surface on the component you are going to align with the assembly).
3. You can select Remove or Add at any time:
◦ To delete a placement constraint for the component, select one of the constraints listed and click Remove.
The system deletes the selected constraint from the current list and updates the message in the STATUS area. You may need to add a new constraint.
◦ The Retr Refs option appears when you redefine a component in a simplified representation, and that component depends on components that are not in the simplified representation. Click Retr Refs to retrieve any other components that define the location of the component.
◦ To add a new constraint to the current list, click Add. Select a type of constraint from the Constraint Type list. Select a reference on the component and a reference on the assembly, in either order, to define a placement constraint. Click Related Links for detailed information.
4. After you redefine the constraints for the active component, click
