Chapter 6 Viewing and Editing Roads in Section View

The following illustration shows the Slope Control dialog box, which

you access from the Edit Design Control command.

Key Concepts

■

If you just want to use simple slopes, you only need to use the

Edit Design Control command. Simple slopes use the typical cut

and fill slope values.

■

Depth control slopes can use different slopes in cut and fill for

various depth ranges based on the depth slope tables that you

create from the Cross Sections menu, by choosing Design

Control

➤

Depth Slope. With this option, the depth of cut or fill

is determined for each section and the appropriate slope is used.

■

You can apply benching to simple or depth control slopes

based on height criteria. You can define the width and grade

of the bench.

■

Stepped control slopes are a variation on depth control slopes.

Instead of finding the appropriate value for the current depth

and applying it as a constant, the slope changes as it passes

through each depth range.

■

Surface control slopes can be applied in cut situations only and

are based on the different existing ground surfaces that they

pass through.
