Splines on Surfaces

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.

Sketching Splines on Surfaces

To sketch a spline on a surface:

  1. Open a sketch on a surface model.
  2. Click Spline on Surface Tool_Spline_on_Surface_Sketch.gif (Sketch toolbar) or Tools > Sketch Entities > Spline on Surface.
  3. Sketch a spline on surface.

    Splines need not extend from profile to profile.

  4. Click PM_OK.gif.
