Drawing a closed spline

You can draw a closed spline, which is a spline for which the start point and endpoint are the same. Because the spline is closed, you specify only one tangent.

To draw a closed spline

  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. Specify as many more points as you want.
  5. When you have finished, in the prompt box, choose Close.
  6. To complete the command, specify the tangent point.
