Chapter 4 Working with Cross Sections

Creating Finished Ground Cross Sections
After you have created design templates, you need to apply these templates to
the existing ground cross sections. Using the Design Control commands, you
can apply a selected template or templates to the existing ground surface and
match the template into the existing ground.
Prerequisites for Applying Templates to Existing
Ground Cross Sections
Before applying the template to the existing ground cross sections, you must
have completed the following minimum requirements:
n
Define a horizontal alignment
n
Sample the existing ground profile from either a surface or from a file
n
Create the profile
n
Define the vertical alignment for the finished centerline
n
Sample the existing ground cross sections from either the surface or a file
n
Draw, define, and edit the necessary templates
n
Draw, define, and edit the necessary subassemblies
Designing Roadway Slopes with Templates and
Cross Sections
You can change the slope settings and the slope control for cross sections by
using the Design Control commands. The Depth Slopes command changes the
depth slopes settings. The Stepped Slopes command changes the settings for
stepped slopes. Use the Surface Slopes command when you want to change the
settings for surface slopes.
Changing the Slope Settings
The Edit Design Control command creates cross sections using the information
set in the Design Control Editor. When calculating depth slope, stepped slope,
or surface slope information, it also uses parameters set with the Depth Slopes,
Stepped Slopes, or Surface Slopes commands. For example, a fill situation of
eight feet may use a different slope than a fill situation of five feet.
