Natural Language Alternatives

Instead of using the tool, you can type these commands:

  • Draw a smooth curve through these points
  • Create an organic curved profile
  • Sketch a flowing S-curve

Tips

  • Fewer control points create smoother curves
  • Splines can be difficult to manufacture precisely
  • Consider using arcs for simpler curved profiles
