Besides using rollouts at the NURBS object
level, you can use the NURBS toolbo x to create
sub-objects.
Inter face
Toolbox for NURBS objects
The toolbox contains buttons for creating NURBS
sub-objects. In general, the toolbox behaves like
this:
• Whilethebuttonison,thetoolboxisvisible
whenever a N URBS object or sub-object is
selected and you are on the Modify panel. It
disappears whenever you deselect the NURBS
object or make a different panel active. When
you return to the Modify panel and select a
NURBS object, it reappears.
• You can use the toolbox to create sub-objects
from either the top, object level, or from any
NURBS sub-objec t level.
• When you turn on a toolbox button, you go into
creation mode, and the Modif y panel changes
to show the parameters (if there are any) for the
kind of sub-object you are c reating.
Other NURBS rollouts aren’t displayed w hi le
you create the new sub-object. This differs from
using the NURBS object’s Create rollouts or the
NURBS
rig ht-click m enu (page 1–1084)
.
• Ifyouareatthetop,objectlevelandusethe
toolbox to create a sub-object, you must then
go to the sub-object level to edit the new
sub-object. (This is the same as using the
buttons on the rollouts.)
• Ifyouareatasub-objectlevelandusethe
toolbo x to create an object of the same
sub-object type, you can edit it immediately
after you turn off the create button (or
right-click to end object creation).
• Ifyouareatasub-objectlevelandusethe
toolbox to create an object of a different
sub-object type, you must change to that
sub-object level before you can edit the new
sub-object.
