1152 Chapter 9: Surface Modeling
Tip: Lathe and extrude surface sub-objects can
be based on only a single curve; see Creating
Dependent Surfaces (page 1–1177).Ifyoucreate
dependent curves and then want to use the set
of curves (for example, two parents and a fillet
betweenthem)asthebasisofanextrudeorloft
surface, first go to the Curve sub-object level and
useJointoconnectthecurves.
Creation operations for dependent sub-objects
require you to select one or more parent objects.
In general, you can click and drag, or click and
then click again. You can also use the
H keyboard
shortcut to displa y a Select Objects dialog (page
1–78) for choosing the parent. (The Keyboard
Shor tcut Override Tog g le (page 3–872) must be on
for
H to work this way.)
Toolbox B uttons for Crea ting Cur ves
These are the toolbox (page 1–1083) buttons for
