Bulge Editor 971
Cross Section view
Cross Sect ion view displays an outline of the active
cross sec tion. In
Profile view (page 2–971) ,the
active cross section is show n in a bright red color.
In Cross Section view, you can edit cross sections
to bulge the mesh.
Note: It is possible to select multiple cross sections
in Profile view using either a rectangular selection
region or CTRL+click. This allows you to enter
settings on the
Cross Sections panel (page 2–972)
for all selected cross sect ions at once. Only one
active cross sect ion, however, can be viewed and
edited in Cross Section view. (Selected but inactive

Gray squar e at center—Represents the link at the
center of the c ross section.
Control points—When unselected, are shown as
small black crosses on the control spline. When
selected, they are shown as black squares with a
white center.
Resolution lines—Displayasgraylinesthat
surround the link radially. Control points snap to
these lines as they are posit ioned.
You can increase or decrease the resolution by
changing the Resolution setting. This cont rol is
on the Bulge rollout in Bulge Sub-Object. The
CrossSectionview,however,alwaysdisplays36
resolution lines.
Red line—The control spline for the act ive cross
section.

Green li ne—Represents actual mesh deformation.
(Typically this is less exaggerated than the control
spline.)
When yo u drag the time slider or play an
animation, this updates according to the angle of
the limb and the bulge angle parameters.
Orientation bar—The bright yellow radius indicates
the orientation of the “slice ” shown in profile
view. Profile view always shows a vertical profile
of Cross Section view, indicated by the g reen dots
at the top and bottom of the v iew, just outside the
circle that contains the resolution lines. By default,
the orientation bar is level at 3 o’clock. You can
change the Profile view orientation by dragging
the end of the orientation bar (the cursor changes
to a miniature cross sec tion). This lets you view
different angles of the bulge in Profile view.
