Splines sketched on surfaces include standard spline attributes, as well as the following capabilities:
- Add and drag points along the surface.
- Generate a preview that is automatically smoothed through the points.
- Span multiple surfaces if the splines that created the surfaces are tangent.
All spline points are bounded to the surface on which they are sketched.
Use splines on surfaces with:
- Part and mold design, where surface splines enable you to create more visually accurate parting lines or transition lines.
- Complex sweeps, where surface splines facilitate creating guide curves bounded to surface geometry.
