To Decrease the Number of Spline Points with a Deviation Value
1. Click Sparse on the MOD SPLINE menu.
2. Type any positive value for a deviation that causes the spline to be redrawn without one or more of its points.
The resulting spline is displayed in green, and you are informed of the number of points removed.
3. To accept the changed spline, click Confirm on the CONFIRMATION menu.
To reject the changes, click Cancel and type a different deviation value. For each spline, you may need to type several different deviation values before achieving the required result.
