To select shape sub-objects:
1.
Expandtheobject’shierarchyinthestack
display and choose a sub-object level, or click
one of the sub-object buttons at the top of the
Selection rollout.
You can also right-click the object in the
v iewpor ts and choose a sub-object level from
the quad menu: Tools 1 (upper-left) quadrant
>Sub-objects>Choosethesub-objectlevel.
2. Click a selection or transform tool, and then
select sub-objects using st andard click or
region-selection techniques.
Because sub-object selections can be complex,
you might consider using one of the follow ing
techniques to prevent clearing the sub-object
selection by accident:
•Use
Lock Selection (page 3–754) .
• Name the sub-object selection (see
Named
Selection Sets List (page 1–67)
).
To clone s ub-object selections :
• Hold down the SHIFT key while transforming
the sub-objects.
You can clone segment and spline sub-objects,
but not vertices.
To dr aw a spline cage:
1.
Select a segment sub-object on a spline.
2. On the Geomet ry rollout in the Connect Copy
group, turn on Connec t.
3. Hold down the SHIFT key and transform the
selected segment. You can move, rotate or
scale using the transform gizmo to control the
direction.
Notice that with Connect Copy on, new splines
are drawn between the locations of the segment
and its clone.
Tip: Use Area Selection or Fuse before selecting
and moving these vertices. They will not move
together as they do with the Cross-Section
modifier. Or use Fuse to keep the vertices
together.
