If the specified layer does not exist, it is created. The layer set by this command
remains current until a new layer is set either with this command or the
AutoCAD LAYER command.
Rotating the AutoCAD Crosshairs to Match the
Grade of the Ditches and Transitions
This command sets the AutoCAD ORTHO mode on and rotates the AutoCAD
crosshairs to a grade based on the entered value and the vertical exaggeration of
the current profile. The command works by setting AutoCAD SNAP rotation to
the selected grade. This makes it easier to draw lines at the specified grade when
you use the AutoCAD LINE command.
To rotate the AutoCAD crosshairs to match the grade of the ditches and
transitions
1 From the Profiles menu, choose DT Tangents รค Crosshairs @ Grade.
2 At the Grade in percent prompt, enter the 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:
n
Reset the SNAP ROTATION to normal by running the command again and
entering a grade of zero.
n
Reset the ORTHO mode by using the AutoCAD ORTHO command or by
pressing Ctrl - O to select the ORTHO mode on or off.
