Fitting a Shape to Other Geometry

Fitting a Curve to a Cloud of Points

You can fit a curve to a cloud of points or any other type of geometry.


Before you begin: Open an existing 3D shape containg a curve and a cloud of points.
  1. Select the curve you wish to deform by fitting it to the geometry.


  2. Select the target element to which the curve should fit.
  3. In the Fitting area, define the deformation parameters.
  4. Right-click the Free label to impose a continuity constraint: Free, Point, Tangent, or Curvature
  5. Click Fit.
    The curve is projected onto the target geometry.

  6. Repeat the operation to deform the curve step-by-step and to fine-tune the fit.
  7. Optional: Select Automatic trap to reduce the number of points to be taken into account when the target element is a cloud of points containing many points.
  8. Click OK.
    The new curve fit as best the cloud of points.
