Offset Normal to Surface

The OffsetNormal command copies a curve on a surface in the normal direction of the surface so that all locations on the copied curve are a specified distance from the original curve.


  1. Select a curve on a surface.

  2. Select the base surface.

  3. Infinite Plane: Type IP for InfinitePlane options.

  4. Specify the offset distance.

    The selected curve is pulled back to the surface first. The offset distance is calculated from the surface.

  5. Pick a location to set another distance, or press Enter if the offset should be a uniform distance from the original.

Command-line options


Specifies the first point for a distance for the offset if it should be different from the point where the curve was selected.


Reverses the direction. Positive values for the distance follow the direction arrows.
