Understanding Slope or Elevation Targets

Slope or elevation targets are used to control the elevations of one or more components of a corridor. For example, these targets can control the elevations of a roadside ditch to ensure that it drains to a specific point, regardless of the slope of the adjacent road (see Figure 9.10). Profiles, feature lines, survey figures, and 3D polylines can be used as this type of target.
