■ Moving and Posing Figures with Transpose 229Figure 7.5 Drawing an action line from the figure to the background will create the line in the
current view orientation, ensuring it is a straight line. Clicking the endpoint will then let you
place it where desired.
Topology Masking
Figure 7.6 shows a figure with an action line drawn down the arm. If we enter Rotate mode
and drag the endpoint, the entire figure will rotate. This is where masking comes in handy.
By masking everything but the arm, the unmasked areas will rotate around the opposite end
of the action line. Masking can be accomplished with the same methods we have discussed
so far (Ctrl-clicking to paint masks or using a marquee).
Figure 7.6 Rotating an unmasked figure is a global operation. With the body masked, only the
arm rotates.
