Display group
Lattices—When on, displays control lattices in
yellow lines. (You can change the lattice color using
the Colors panel (page 3–799) of the Customize
User Interface dialog.) The Curve CV and Surface
CV sub-object levels also have a local Display
Lattice toggle, which overrides this global setting
at the sub-object level. The Curve CV and Surface
CV settings are independent. In other words, at
the sub-object level you can turn on the lattice for
an object’s curves but not its surfaces, or vice versa.

Ctrl+L overrides the setting of Lattice, toggling
the local Display Lattice setting.

entire surface, e ven if it’s trimmed.

Tra nsf orm Deg rade—When on, transforming a
NURBS surface can degrade its display in shaded
viewports, to save time. This is similar to t he
Degradation O verride (page 1–34) button for
playing animations. You can turn off this toggle so
surfaces are always shaded while you transform
them, but transforms can take longer.

Override Toggle is on):

Tip: You can toggle Ctrl+X during a transform,
as well as before you begin the transform.
NURBS Creation Toolbox—Turn on to display
the NURBS sub-object creation toolbox. See Using
the NURBS Toolbox to Create Sub-Objects (page
1–1083).
