moving or transposing. In Figure 11-86, the image on the left shows
the Transpose action line positioned with the start point at the
deltoid muscle. The midpoint is at the elbow, and the endpoint is at
the hand (not visible). The image on the right shows the arm has
been moved by selecting and dragging the endpoint circle.
Mesh Extraction
Another very interesting new feature for modeling is mesh extrac-

mask selection, a visibility selection, or a layer. The command is
located in the SubTool palette.
Topology
Topology is a great new feature that helps with optimization of a
mesh to use with an external application or even inside ZBrush.
With this feature, you can rebuild the topology (edge loops/flow) of
the mesh to be animated in an external application or remove
