This tutorial demonstrates how to display cross sections of the corridor model surfaces along the centerline alignment. You will create sample lines and then generate the sections.
Cross sections show elevations at sample lines, which are created perpendicular to an alignment. Sections can be derived from surfaces, corridors models, and corridor surfaces. Furthermore, they can be either dynamic or static. When a surface or corridor is modified, dynamic sections are automatically updated. A static section shows the elevations at the time it was created, but does not react to later geometry changes. Similarly, dynamic sample lines associated with an alignment move with the alignment if it is modified.
For more information, see the AutoCAD Civil 3D Help topic Sections.
Topics in this section
- Exercise 1: Creating Sample Lines
In this exercise, you will create a set of sample lines along the alignment.
- Exercise 2: Creating Section Views
In this exercise, you will create a section view for a range of sample lines.
