Smoothing Curves

Curve Smooth lets you smooth a curve, i. e. fill the gaps, and smooth tangency and curvature discontinuities.


Before you begin: Create a 3D shape containing a curve that needs to be smoothed.
  1. In the Curve to Smooth box, select the curve to be smoothed.
    Important:
    • You cannot select a sub-element as curve to be smoothed.
    • You can select several input curves. In this case:
      • The options on the Parameter and Extremities tabs are applied to all input curves.
      • On the Freeze tab, you cannot select sub-elements to be excluded from the smoothing operation. Previously selected sub-elements will be removed from the list when adding further input curves to a single selection.
      • If a support surface is selected, it must contain all input curves. Topology simplification will be applied to all input curves.

    On the curve are displayed texts indicating its discontinuities before smoothing and the type of discontinuity (point, curvature, or tangency) and their values.

  2. Click Preview to display the curve discontinuities that are still present after the smoothing operation, and whether they are within or outside the threshold values (yellow or red flag).
  3. Click the Freeze tab and select sub-elements of the curve that should not be smoothed.
    Important:
    • External elements cannot be selected as sub-elements.
    • Freeze is not supported in case of multi-selection.
  4. Click the Extremities tab and define the continuity conditions at each curve's extremity.
  5. Click the Visualization tab to define the way the messages are displayed on the smoothed element.
  6. Click OK.
