180 | Chapter 13 Viewing and Editing Roads in Section View
■ Draw, define, and modify the necessary templates and subassemblies
Key Concepts
■ You can use two methods to modify the cross sections after you process
them. You can use the Edit Design Control command to modify a range
of cross sections, or you can use the View/Edit Sections command to
change individual sections.
■ If you want to apply superelevation or transition control to finished
ground cross sections, the template must contain transition and superele-
vation control locations. You define these locations using the Edit
Template command. You can then apply superelevation factors and
specify vertical and horizontal transitions when widening or altering the
roadways characteristics.
■ You can use two methods to process cross sections. If you change any of
the cross section design control when you are using the Edit Design
Control command, then the sections are processed automatically as you
exit the command. You can also process cross sections manually by choos-
ing Cross Sections
➤ Design Control ➤ Process Sections.

2 If you are applying superelevation to the alignment, then
set up the superelevation parameters. From the Cross
Sections menu, choose Design Control
➤ Superelevation
Parameters.
NOTE You can set up the superelevation parameters at
any time during the design process.

Superelevation Settings
3 In the Superelevation Control dialog box, click OK to
display the Save Status dialog box, and then click Yes to
apply superelevation parameters to all existing cross
sections. The Superelevation Section Sampling dialog box
is displayed.
4 In the Superelevation Section Sampling dialog box, you
can choose to sample sections at key superelevation
stations. Select the Sample These Stations check box, set
the swath widths, select the surface(s) to sample, and click
OK.
