left and right of the centerline when you sampled the existing ground, then you
can also create profiles of these alignments with the Full Profile command.
6 Under Station Range, in the Start and End boxes, set the station range.
The defaults are the defined starting and ending stations for the current
alignment. This range defines the range of the current alignment for which the
profile is created.
The Datum Elevation Entry section of the dialog box lists the maximum and
minimum elevations for the alignment within the defined station range.
7 In the Datum box, enter the datum elevation. This is the base elevation of the
plotted profile.
The datum elevation default is based on the minimum elevation in the profile.
8 Using the Vertical scale box, edit the vertical scale.
The vertical scale is compared to the horizontal scale set during the drawing
setup to determine the vertical exaggeration of the profile. If the horizontal
scale is 1=50', a vertical scale of 5.00 (1=5) produces a vertical exaggeration of
10.
9 Under Profile creation parameters, click the appropriate option to specify the
direction in which the profile is to be drawn, to the right or to the left.
10 Select the Import Left/Right profiles check box to import the existing ground
profiles to the left and right of the centerline.
You can import these profiles only if you selected the Sample left/right check
box in the Profile Sampling Settings dialog box before you sampled the profile
information. If this check box is cleared, only profile surfaces are imported.
11 Select the Import grid check box to import a profile base grid.
12 Set the horizontal spacing, vertical spacing, and grid height in the appropriate
boxes.
13 Click OK.
14 Select a starting point for the profile:

already generated this profile enter Y for Yes in response to the
Delete existing profile layers
prompt.
Entering Yes in response to the Delete existing profile layers prompt, erases all
entities on the profile layers defined in the EG Layers and FG Layers commands.
Removing the old profile also replaces the profile information block to reflect
the new information. Enter N for No if a profile does not exist.
