Example: Offset of a Curve On Surface
Begin with a curve on surface (COS).
1. Curve on surface
The next figure shows an offset of the COS. The offset curve lies on the same surface as the COS.
1. Original COS
2. Offset curve lies on the same surface
The next figure shows an offset of the COS. The offset curve is normal to the surface on which the COS lies.
