Inter face
Sur f ace Offset Cur ve rollout (creation time)
Offset—The amount by which t he curve is offset
from the surface on which the parent curve lies.
Sur face Offset Curve rollout (modification time)
Offset—The amount by which t he curve is offset
from the surface on which the parent curve lies.
This parameter is animatable.
Replace Cur ve—Lets you replace the parent curve.

Iso curves in the U and V dimensions
U and V iso cur ves are dependent curves created
from the iso (isoparametric) lines of a NURBS
surface. You c an use U and V iso curves to trim
surfaces (page 1–1080).
Procedure
To create an iso curve:
• Turn on U Iso Cu r ve or V Iso Cur ve ,
then dr ag over the surface.
The iso lines are highlighted in blue as you drag.
Click to create the curve from the highlighted
iso line.
