. Positions a movable part or model instance so that a selected face is parallel to a selected face of a fixed instance.
. Positions a movable part or model instance so that a selected face is parallel to and a specified distance away from a selected face of a fixed instance.
. Positions a movable part or model instance so that a selected edge is parallel to a selected edge of a fixed instance.
. Positions a movable part or model instance so that a selected edge is parallel to and a specified distance away from a selected edge of a fixed instance.
. Positions a movable part or model instance so that the axis of revolution of a selected face is coincident with the axis of revolution of a selected face of a fixed instance.
. Positions a movable part or model instance so that a selected point is coincident with a selected point of a fixed instance.
. Positions a movable part or model instance so that a selected datum coordinate system associated with the instance is parallel to a selected datum system of a fixed instance.
Constraints position one instance relative to another; as a result, constraints cannot be applied until your assembly contains two or more part or model instances.
You may find it more convenient to access the constraint tools using the Assembly module toolbox. For a diagram of the tools in the Assembly toolbox, see Using the Assembly module toolbox.
