Automatically adds spans to the high curvature parts of a curve, resulting in more CVs in those areas and so easier control of the curve’s shape.

Add edit points to a curve based on its curvature

1. Choose Curve Edit > Rebuild Curve ❒.
2. In the Rebuild Curve window:
   • In the Rebuild Type pop-up menu, choose Curvature.
   • Turn Auto Recalc on.
     Tip

     Set Max Spans Type to Absolute if you don’t want the number of spans to exceed a certain number (Max Spans), otherwise use Relative.

3. Click the curve(s).
   
4. Click Go.
   
5. Use the Tolerance control to adjust how many edit points the tool should add to the curves. A low value inserts more new edit points. A high value adds fewer new edit points.
