To rotate the AutoCAD crosshairs to match the grade of the finished
ground centerline
1 From the Profiles menu, choose FG Centerline Tangents ä Crosshairs @ Grade.
2 At the Grade in percent prompt, enter the appropriate grade (without the %
character).
A positive value indicates a tangent going up; and a negative value indicates a
tangent going down.
3 Before running any other command, reset the SNAP rotation and ORTHO settings.
You can set the SNAP ROTATION to normal by re-running the command and
entering a grade of zero. Reset the ORTHO mode using the AutoCAD ORTHO
command, or press Ctrl - O to select the ORTHO mode on or off.
The following illustration shows rotated AutoCAD crosshairs:
