Specify the Range to Edit the Curve Data

  1. If Snap is turned on:
    1. Snap forces the Range values to be existing points on the selected curve. Move the range bars on the screen to find the curve point.
    2. Or, use the arrows to increase or decrease the From and To values. The From and To values are restricted to the curve point.
      Note: Entering range values directly into the From and To fields is not allowed when Snap is turned on. The From and To values are restricted to the curve point.
  2. If Snap is turned off:
    1. Enter range values in the From and To fields.
    2. Or, use the arrows to increase or decrease the From and To values. The value listed in the Step field is the amount by which the From and To values are increased when you use the arrows.
      Note: The From and To values are not restricted to the curve point.
  3. Select and drag a range bar on the screen in either case.
