position and shape the new geometry by
hand. (It's good to get in the habit of

these settings. The tiny bit of extra time it
takes more than makes up for the headache
of finding a half-buried, “dismembered” set
of points much later on in your work, the
results of an erroneous Smooth Shift opera-

BandSaw
The best characters are made up of loops
(or bands) of four-point polygons. The
BandSaw tool can be used to subdivide
these loops into smaller bands. You can
think of it as knifing along the path created
by the band of the polygons.
When you have Enable Divide active in
the BandSaw window, the tool not only
selects
the band of polys (along the U or V),
it also creates more
segments
in that
selected band with respect to the

. You create and position these
