Viewing and Editing Roads in Profile View
After you draft and define a horizontal alignment for a road, you can create
a road profile (also known as a vertical alignment or long section) that repre-
sents the existing and finished grades along the roadway centerline. To work
in profile view, create an existing ground profile for a defined alignment by
sampling elevation data from a surface. You can then create the existing
ground profile in the drawing, and draw the vertical alignments and vertical
curves that represent the finished ground profile design.
After you draw a finished ground vertical alignment, you must define it in
the same way you define a horizontal alignment. The finished ground eleva-
tions are used later to calculate the elevations for the roadway cross sections.
Storage Location of Alignment and Profile Data
The alignment folder (c:\Land Projects<Version Number>\<project
name>\align) contains all the files for the horizontal alignments in the
project. Each alignment that has a profile or cross section has a unique sub-
folder under the \align folder. This subfolder contains all the profile and cross
section files for the alignment. For example, if you have an alignment called
MAIN ST in the project P101, you can find all the profile and cross section
files in the \P101\ALIGN\MAIN ST folder.
Additional profile settings are located in the <dwgname>.dfm file that is
located in the \<project name>\dwg folder. The profile settings contain the
drawing defaults for profile layer names, scales, and label increments.
