Working with Templates
To create finished ground cross sections, you must use a template. A template
represents a finished surface, such as a road, channel, dam, or railway bed
surface and its subsurface layers, such as asphalt, concrete, and granular
materials, with optional subassemblies for shoulders and curbs.
You can draw a template using an exaggerated scale (based on the drawing’s
vertical scale) to better visualize the surfaces. After drawing a template, define
the template and the design control, and then generate the cross sections.
Sections are generated wherever an existing ground cross section has been
sampled.
All templates have a defined finished ground reference point that can posi-
tion the template on the cross section using the horizontal alignment and
the finished ground vertical alignment (the finished ground centerline
profile) for control. This reference point is usually the crown of the roadway,
as shown in the following illustration.

sections by selecting a command from the Cross
