1178 Chapter 9: Surface Modeling
Tip: Lathe and extrude surface sub-objects can
be based on only a single curve. If you have
dependent curves and want to use the set of curves
(for example, two parents and a fillet between
them)asthebasisofanextrudeorlathesurface,
firstgototheCurvesub-objectlevelanduseJoin
to connect the curves.
Creation operations for dependent sub-objects
require that you 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.)
