Offset Curve on Surface

The OffsetCrvOnSrf command copies a curve or surface edge on a surface so that all locations on the copied curve are a specified distance from the original curve and lie on the surface.


  1. Select a curve on a surface.

  2. Select the base surface.

    The picked location decides the initial offset direction.

  3. Type the offset distance.
