Location: Create>Advanced Splines>Project to Surface
The projection of any curve onto a surface will result in a cubic spline entity; regardless of the entity type of the curve projected.
Surface Offset Value
Specify a value for the Surface Offset.
Select either Normal to Surface or Skewed (Specify Direction) for the Projection Method.
Trim Projected Curve to Boundaries
When this setting is checked, the projected curve will be trimmed to the boundaries of the surface. If the projection falls off the edge of the surface, it will be projected onto the theoretical linear tangential extension of the surface.
