Falling Lines

Falling lines are shown by skewboxes in the same way as other skewed lines. If the amount of fall is less than the current fall limit, the fall is shown by a wedge-shaped symbol on the pipe showing the direction of fall, and the word FALL followed by the amount of fall in degrees. The symbol is known as a fall arrow.

By default, the fall limit is 5°. This limit can be changed, or expressed in different units using the FALLINGLINES command. The accuracy of reporting the fall amount can be varied.

The fall arrow and slope method can be switched off completely, and all falls will then be shown as skewboxes.
