Specifying fit tolerance

By default, the spline passes through all of the control points. When you draw a spline, you can change this by specifying the fit tolerance. The fit tolerance value determines how closely the spline fits the set of points you specify. For example, a spline fit tolerance value of 0 causes the spline to pass through the control points. A value of 0.01 creates a spline that passes through the start and endpoints and within 0.01 units of the intermediate control points.

To specify the fit tolerance

  1. Do one of the following:
    • Choose Insert > Spline.
    • On the Draw 2D toolbar, click the Spline tool ().
    • Type spline, and then press Enter.
  2. Specify the first point of the spline.
  3. Specify the second point of the spline.
  4. In the prompt box, choose Fit Tolerance.
  5. To accept the default of 0.0000, press Enter.
  6. To specify a different fit tolerance, type the number, and then press Enter.
  7. Specify the additional points you need to draw a spline or a closed spline.
