Adding a Guardrail
The Guardrail object is used to create a freeform
protective rail that is found on many busy or dangerous roads. The guardrail
uses standard measurements and can be modified in height and in post spacing.
To add a guardrail:
Click the Add Guardrail button found near the top of the screen
under the Road tab.
Draw the guardrail by clicking the left mouse button to add points. Press the
Backspace key to remove the last point added, or press the Esc key
to cancel. If you would like to input the distance and angle manually, place at
least one point and then press the Enter key.
To finish drawing the guardrail, right-click to place the last point. The
guardrail will be constructed to the left of the line that was drawn.
In the picture below, a guardrail is used to line a ridge
that borders a lake.
Guardrails can be added in either the Plan view or the Perspective view,
but are easiest to add in the Plan view.
