OCAD Methods

Defined as line symbol 516.0, use the line tool, clicking at each pylon.

Drawing Considerations

Often running in a ride / clearing that may be overgrown

If the line runs alongside a better navigation feature, such as a boundary or track, then the power line may be left off.

To get a true straight line between the pylons; define the corner pylons first and then add middle ones by adding corner points on the defined line.
