To Create a Spline and Specify Tangency
1. Click Sketch > Spline.
2. Specify a tangency condition for the ends of the spline. The angle of tangency is measured from the horizontal in the counterclockwise direction.
3. Select one of the following on the TANGENCY menu:
None—Creates a spline curve with no tangency specified at its endpoints.
Start—Creates a spline curve with tangency specified at its startpoint.
End—Creates a spline curve with tangency specified at its endpoint.
Both—Creates a spline curve with tangency specified at both ends.
4. Pick the startpoint for the spline.
5. Specify the tangency angle, if necessary.
6. Continue to select spline points.
7. Middle-click to end the spline at the last selected point..
8. Specify a tangency angle, if necessary.
