The NSurf Sel (NURBS Surface Select ion)
modifier lets you place a
NURBS (page 1–1079)
sub-object selection on the modifier stack. This
letsyoumodifyonlytheselectedsub-objects.
Also, selected curve sub-objects are shape objects
that you can use as paths and motion trajectories.
If a NURBS surface object is
nonrelational (page
1–1118)
, N Surf Sel c an’t select the sub-object levels
Curve, Curve CV, or Point. NURBS surfaces are
nonrelational by default. You can make the surface
relat ional by turning on Relat ional Stack on the
object’s General rollout.
NSurf Sel can select any kind of NURBS
sub-objects except imports. Each sub-object
selection is of one particular sub-object level only.
Note: The NSurf Sel modifier doesn’t support
copyingandpastingselectionsas
Mesh Select
(page 1–710)
does. Copying and pasting mesh
selections is based on vertex indexes. NURBS
selections are based on object IDs, which are
unique to each mo del.
