Edit Curve on Surface Dialog 1229
Inter face
Detach a s—Lets you assign a name 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,
detachingaUloftconvertsittoaCVsurface.
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 cur ves that define it.
Default=on.

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.
You can edit multiple CV on surface (page 1–1172)
or Point on surface (page 1–1175) curves, but you
can’t edit both ty pes of curves at the same time.
The point whose surface you first click is shown as
a blue square in the dialog as well as in viewports.
As you draw the curve, it appears interactively in
