Create an offset copy of a curve or surface

Creates a copy of a curve or surface that is offset from the original (every point on the copy is a specific distance from the corresponding point on the original).

Create an offset copy of a curve

1. Do one of the following:
   • Select a curve or isoparm, then choose Edit Curves > Offset > Offset Curve.
   • Select a curve-on-surface, then choose Edit Curves > Offset > Offset Curve On Surface.
2. An offset curve is created at a default offset distance of 1.0.
3. In the toolbox, click the Show Manipulator tool and use the manipulator to change the offset distance.

   

Create an offset copy of a surface

1. Select the surface.
2. Select Edit NURBS > Offset Surfaces > .
3. Do one of the following:
   • To preserve surface curvature, set Method to Surface Fit.
   • To preserve CV layout, set Method to CV Fit.
4. Enter a distance to offset. You can change the distance interactively in the channel box or attribute editor after you offset.
5. Click Offset.
