Creating and Editing Templates
and Subassemblies
To create finished ground cross sections, you design a template for the
alignment and apply it to the alignment. For curb or shoulder design, you can
attach subassemblies to a template.
A template is a typical section representing the finished ground design elements
such as asphalt, concrete, and granular materials. After you draw and define the
template, you can apply the template to the existing ground cross sections.
All templates have a defined finished ground reference point which is used to
position 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.
Subassemblies are elements such as a shoulder or curb that you can attach to
the template. Subassemblies differ from normal template surfaces in that they
will vary depending on whether the template is in a cut or fill situation. After
you have created a template, you must edit it to define datum, superelevation,
and transition points on it. You can also edit the template to change subgrade
depths, to change the shape of the template, and so on.
All templates and subassemblies are stored in the path specified by the Set
Template Path command. After you define templates and subassemblies, you
can use them for any project you are working on.
