Sections

Use sections (also referred to as cross sections) to provide a view of the terrain cut at an angle across a linear feature, such as a proposed road.

Typically, sections are cut across horizontal (plan) alignments at a specified station interval using specified swath widths. These sections are then plotted, individually for a station, or as a group for a range of stations.

AutoCAD Civil 3D handles the creation, management, and plotting of sections with the following components:

• Sections. Terrain elevations that cut across surfaces, including corridor surfaces, which are associated with a specified sample line group. Elevations are sampled at each of the sample line XY vertices and also at locations where the vertical plane defined by the sample line intersects with surface edges.
• Section Views. For each sample line, views displaying some or all of the sections sampled at that sample line. This graphical view has both horizontal limits based on the length of corresponding sample line and vertical values based on the minimum and maximum elevations from the set of sections it is displaying.
• Section Sheets. You can generate production-quality section layouts for plotting. For more information, see To create layouts for section plotting.

Topics in this section

• Understanding Sections

  You can use sections to examine existing and proposed surface elevations sampled across an alignment at defined station intervals.

• Sample Line, Section, and Section View Settings

  You can change the default style and name format settings for sample lines, sections, and section views.

• Sample Line, Section, and Section View Styles and Display

  Styles control the way a sample line, section, and section view is displayed in a drawing. Sample lines, sections, and sections views have label styles that control the appearance and behavior of their labels in a drawing.

  AutoCAD Civil 3D enables you can to easily create, manage, and edit sample lines and sections.

• Creating and Editing Section Views

  AutoCAD Civil 3D enables you can to easily create, manage, and edit section views.
