Changing the End Point Tangency of a Spline

  1. Click the Select tool in the Edit group on the Design tab while in 2D mode.
  2. Select the spline in the Design window.
  3. Set the value for Periodic in the Properties panel:

    • True: If you change this property to True, the tangencies of the beginning and end of the spline curve will match to create a closed curve. If a spline curve is open and you set the property to True, the spline will be closed, as shown here:

    • False: If you change this property to False, the end tangencies of a closed curve don't match. If a spline curve is closed and you set the property to False, the curve will become teardrop-shaped because the end points will no longer be tangent, as shown here:
