You can create the following constraints:
Tie constraints that tie two separate surfaces together so that there is no relative motion between them.
Rigid body constraints that allow you to designate a collection of regions as a rigid body.
Display body constraints that allow you to designate a part instance that will be used for display only.
Coupling constraints that allow you to constrain the motion of a surface to the motion of a single point.
Shell-to-solid coupling constraints that allow you to couple the motion of a shell edge to the motion of an adjacent solid face.
Embedded region constraints that allow you to embed a region of the model within a "host" region of the model or within the whole model.
Equation constraints that describe linear constraints between individual degrees of freedom.
To create constraints:
From the main menu bar, select Constraint
Create.
Tip:
You can also create a constraint using the 
tool in the Interaction module toolbox.
In the Create Constraint dialog box that appears, do the following:
Name the constraint. For more information about naming objects, see “Using basic dialog box components,” Section 3.2.1.
Select the desired constraint type, and then click Continue.
Click Continue to create the constraint and to close the Create Constraint dialog box.
If applicable, select the region to which to apply the constraint. For more information, see Chapter 6, “Selecting objects within the viewport.”
In the editor that appears, enter any data necessary to define the constraint.
For detailed instructions on creating different types of constraints, see the following sections:
