TIP First select the link to rotate, then click Rotate. While the Motion panel is
active, Biped sets the transform managers to reflect the degrees of freedom of
that link. For example, if you select the pelvis and then click Rotate, Biped changes
the coordinate system to Local and turns on the Y axis constraint. (For joints that
have more than one degree of freedom, you might later need to change the axis
constraint setting.)
To rotate the biped pelvis in all three dimensions, refer to
Pelvis as Ball Joint
on page 4244.
Biped Motion Constraints
Some biped parts have special-case conditions that govern how you can
transform them, as described in the table and sections that follow.
