Tool SettingEffect
Distance

  • A positive distance extends the line.

From End

(Applies for Distance off only) If on, the extension, or shortening, of the line is relative to the nearest endpoint to the identification point.

If off, the extension, or shortening, of the line is relative to the origin point of the line, no matter where it is identified..

To extend or shorten a line by entering a data point
  1. Select the Extend tool.

  2. Identify the line near the endpoint to modify.

  3. If Distance is on, accept the modification.
    or
    If Distance is off, enter a data point to define the new endpoint.

    In each example, identify the line (1) and accept the extension (2).

    Top: Defining the new endpoint graphically when Distance is off. Bottom: Defining the new endpoint when Distance is on. If the Distance, denoted by “D,” is negative, the line is shortened. If the Distance is positive, the line is lengthened.
