Delete Original Curves—
This is available only if the
surface was already a U loft or UV loft. When on,
Convert Surface deletes the original loft curves
when you click OK. When off, the original curves
remain where they are. Default=off.
CV Curv e : Cl o s e Curve D i alo g
Create panel > Shapes button > CV Cur ve button > In
viewports, draw a CV curve and click to create a CV in the
same location as the first CV in the curve.
Modify panel > Select NURBS object. > NURBS toolbox
> Create CV Curve > In viewports, draw a CV curve
sub-object and click to create a CV in the same location
as the first CV in the curve.
This dialog lets you create a closed CV curve when
you click to create a CV in the same location as the
cur ve’s first CV.
Inter face
Yes—C loses the curve and ends curve creation.
No—Keeps the curve open and does
not
end curve
creation.
Detach Dia log (NURB S)
Modify panel > Select a NURBS sub-object. > Cur ve
Common or Surface Common rollout > (optional) Copy
toggle > Detach button
This dialog appears when you use Detach to
create a new top-level NURBS curve or surface
sub-object.
Interf ace
Detach as—Lets you assign a n ame to the new
object. By default, the name is "Curve" or "Surface"
followed by a sequence number.
This option is unavailable when Detach To
Element is on.
Relational —This toggle affects dependent objects.
When off, detaching a dependent sub-object
makes it an independent object. For example,
detaching a U loft conv erts it to a CV surface.
When on, detaching a dependent sub-object also
detaches the objects on which it depends, so the
object remains dependent. For example, detaching
a U loft also detaches the curves that define it.
Default=on.

edit regular curves in a viewport. The main part
of the dia log is a two-dimensional view of the
surface. The controls provide typical curve editing
functions.
This is a modeless dialog. You can use the main
3ds Max window while Edit Curve on Surface
remains open. However, if you select a different
kind of curve or a sub-object that isn’t a curve, the
dialog closes.
