Insert Constraint
The insert constraint causes a circular edge on one component to be concentric
and coplanar with a circular edge on another component. The offset value for
an insert constraint is the distance between the two faces containing the
circular edges. For example, you can use this constraint to place a pin or a
capscrew in a hole.
Specifies the direction of the face normal for the planes
containing the circular edges. An arrow indicates the

normal direction. The opposed solution has the two
planes facing each other, as in a mate constraint. An
aligned solution has the normals pointing in the same
direction.
Motion Constraints
You can add motion constraints to components in an assembly to animate
the motion of gears, pulleys, rack and pinions, and other devices. By applying
motion constraints between two or more components, you can drive one
component and cause the others to move accordingly.
Two types of motion constraints are possible:
Use to apply motion constraints to wheels, pulleys,
and gears.
Rotation
Apply motion constraints to rack and pinion or wheel
and rail components. These constraints are bidirection-
al and accept a specified ratio or distance.
Translation
Motion constraints do not maintain positional relationships between
components.
Fully constrain assembly components before you apply motion constraints.
Then, suppress constraints that restrict the motion of the components you
