This command allows you to create profile files and is similar to Design Road Profile. The only difference is that Enter Existing Profile does not ask for vertical curves. The procedure is to first specify the on-screen grid and then enter or pick the stations and elevations. The profile is drawn as it is entered.
Notice that the station, elevation, and slope at the current
position
of your cursor crosshairs is displayed at the bottom of the side-bar
menu. These values will update whenever the crosshairs move except
after selecting
either the side-bar or top menu.
