Working with Templates

The following illustration shows the points you need to pick when

drawing symmetrical and asymmetrical templates.

■

To apply transition and superelevation regions on the template,

you must edit the template after you define it.

■

Templates can be made up of normal and subgrade surfaces.

Normal surfaces are the elements of the template which make up

the main part of the template such as pavement surfaces, median

islands, shoulders, and curbs. Subgrade surfaces are linked to the

normal surfaces, but use separate design parameters to control the

grade and depth of the surface. A typical subgrade surface is made

up of granular materials, such as gravel, and generally represents

materials lying directly over the subgrade (limit of excavation).

■

While curbs and shoulders can be defined as part of the template,

you can also draw these items separately and define them as

subassemblies. Then, when you are defining the template, you can

attach the subassembly to the template definition.

■

You can use template point codes to insert points into the

drawing based on template points, such as the right-of-way and

edge-of-pavement.
