whatever the widening says the width of the first segment should be

at the station where the template is inserted.
Also notice in Figure 5 that we have defined a widening with the start
width the same as the end width. This can be a handy tool to use if

you need to widen the road for a relatively long distance but also need
to change the template segments outside the first segment. Using a

widening as shown enables you to use any template to modify the

outside segments while retaining the same roadbed (first segment)
width.

Super Elevations

The examples above show how widenings interact with templates.

Super elevations work with templates in the same way, except
instead of the width of the first segment being modified, the cross

slope for the first segment is modified.

Creating Templates

The information for a single template is stored in a separate file with

a TP5 extension. Template names are limited to eight characters plus
the extension so that they can be used in DOS-based data collectors.

Each template stores information on the cross section for one side of

the road.

A road can have as many templates as necessary, but each side of the

road must only use templates with the same number of segments.

Once the first template is selected, Survey Pro will only let you select
from additional templates that have the same number of segments as

the first template.

A template can be used on either side of the road. They are not right

or left specific. A road could contain only one template, which would

be used for both the right and left sides, but can also contain as many
templates as necessary.
In this example, we will create a single template that contains a

roadbed, a curb, and a ditch. Each segment will be defined in order,
starting from the centerline and working toward the edge.
