What are the six degrees of freedom?
What will be an ideal response?
Each time you bring an instance of a component into an assembly, you introduce six degrees of freedom (DOF). The instance will have a set of coordinate axes associated with it, and the six new DOFs will correspond to the three translational DOFs (distance along X, Y, and Z from the instance origin to the base component origin) and to the three rotational DOFs (rotations about X, Y, and Z) relative to the coordinate planes associated with the base component.
