About Constraints
Use constraints to define the movement of a manikin as you would for any assembly. When a segment is fully or partially locked, it is locked against another segment, so they move together.
When you click 
Reach or 
Look At, constraints are automatically created between the manikin and the geometry in the scene. These constraints can be captured and saved in a snapshot for analysis.

Manikin Constraints node.
Manikin Constraints node.In the Manikin Tree, when the DOFs (degrees of freedom) of a manikin segment or manikin segment group are fully or partially locked (constrained), the icons show their status:
• The 
manikin segment icon changes to 
when the segment is locked, or to 
when the segment is partially locked.
