that are connected in space.
Surface sub-object selection controls
Single Sur face—Clicking or transforming a surface
selects only a single sur face sub-object.
All Connected S urf a ces—Clicking or transforming
a sur face selects all surface sub-objects that are
connected within the NURBS object. To be
connected, two surfaces must have all the CVs on
a shared edge f used between them, or one surface
must b e a connected dependent of the other (for
example, a blend or a cap).
Name—Shows the name of the currently selected
surface. It is disabled if you have selected multiple
surfaces.
By default, the name is the name of the surface type
("CV Surface," "Point Surface," "Blend Surface,"
and so on) followed by a sequence number. You
can use this field to give the surface a name that
you choose.

Delete—Deletes the selected surface sub-objects.
Mak e R igid—Makes the surface rigid. The on ly
editing allowed on a rig id surface is to transform
it at the Surface sub-object level. You can’t move
a rigid surface’s points or CVs, or change the
number of points or CVs.
