and choose Relations.
Viewing Constraints and Their Information
You can identify the objects that have constraints on their parameters in the 3D views and in the schematic view. As well, you can use a constraint query to get information about the constraints on an object.
To view constraints in a viewport
• In any viewport title bar, click the eye icon and choose Relations.
- When you select a constrained object, a white line linking it to its constraining object is displayed. The link is labeled with the type of constraint, such as Pos for a position constraint.
- When you select a constraining object, a light purple (lavender) line linking it to its constrained object is displayed.
For direction constraints, a link with an arrow at one end shows the relationship between the constrained and constraining object (the large arrow points to the constraining object).
To open the constraint property editor
• Select the link line and press Enter. This always selects the constraint in the context of the constrained object.
To view constraint relations information
1. Click the eye icon in a viewport and choose Visibility Options (or press Shift+s).
2. From the list of options on the Attributes page in the Visibility Settings property editor, you can choose to show Relations icons or Relations Information for selected or unselected objects, or both.
The relations information shows whether the constraint is deactivated (off), the constraint’s priority (the order in which is was applied in the case of multiple constraints—1, 2, 3, etc.), and its blended weight value (if multiple constraints are blended).
If there are multiple offsets on the object’s constraints, two arrows and their distance displays tell you the length of each link.
To view constraints in the schematic view
• Open a schematic view and choose Show > Constraint Links, then select a constrained or constraining object.
A constrained object has the letter C above its node. A green arrow with the name of the constraint type (such as Direction, Position, UpVector, etc.) links objects that are affected by a constraint.
When a parameter (global transformation) is controlled by a constraint, the parameter’s animation icon changes from its default green box to a letter C and a connection 
. See The Animation Icon for more information about the different states of the animation icon.
You can use a special constraint query in the spreadsheet to show the constraints on an object. This query makes it easy to get an overview of constraints for selected objects, as well as activating/deactivating a constraint, changing the blend weight, and seeing the constraining objects (inputs).
To select the query
1. Select one or more constrained objects.
2. Open a spreadsheet (press Alt+3) and choose Query > Constraints.
For more information, see The Spreadsheet [ Interface and Tools ].
Finding Constraint Elements in the Explorer
You can select a constrained object and then use an explorer to find its constraint properties.
• Choose Explore > Constraints from the Select panel to open up a contextual explorer for the object.
or
• In the explorer, press E to show only the properties of the currently selected objects.
Expand the constrained object’s Kinematics > Constraints branch to see any constraint that is applied. Click the constraint’s name to select it, or click the constraint’s icon to open its property editor for changing any attributes, activating or deactivating it, etc.
|
• Right-click the Constraints folder to open a menu where you can choose Properties to open a property editor showing all constraints in this folder. You can also activate, deactivate, or delete all constraints in that folder using the menu. • As with other operators in Softimage, the constraint that is applied last is displayed at the top of the stack in the explorer. • You can’t rename constraints. However, if you have multiple constraints of the same type on an object, each constraint name is differentiated by a number in brackets, such as PosCns[3]. |
