Header

Every constraint has a header at the top:

Constraint header

/ Expand/Collapse

Show or hide the settings of the constraint. Collapsed constraints remain active.

Icon

Icon representing the constraint’s type. If this icon is red, one or more settings are not correctly filled in and the constraint has no effect.

Name

Initially this is simply the constraint type, but it can be customized to something more specific.

Enabled

Enable or disable the constraint. Disabling a constraint turns off its effects while keeping its settings around for the future.

Another way of disabling a constraint is to set its Influence to zero. Unlike the Enabled setting, this can be animated.

Extras

Apply Ctrl-A

Applies the constraint’s result to the object’s/bone’s own transformation, then deletes the constraint.

Warning

Applying a constraint that is not first in the stack will ignore the constraints before it, which may produce undesired results.

See also

Apply Visual Transform to apply the combined result of all constraints without deleting them.

Duplicate Shift-D

Creates a copy of the constraint just below current one.

Copy to Selected

Copies the constraint from the Active object to all selected objects.

Move to First/Last

Moves the constraint to the first or last position in the stack.

Delete X, Delete

Delete the constraint from the stack. Its settings will be lost and it will no longer affect the object/bone.

Move

Drag to move the constraint up or down in the stack. Since the stack is evaluated from top to bottom, moving a constraint can significantly affect the final outcome.
