Exercise 1: Creating Sample Lines - Autodesk CIVIL3D - CIVILDESIGNCOMP 2007 SLM CD Tutorials Manual

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.
TIP You can use the workflow that is demonstrated in this tutorial to create section
views from a corridor Xref. Section views created from an Xref can be dynamically
linked to the corridor model; if the corridor model in the Xref drawing changes,
the section views update automatically.
For more information, see the AutoCAD Civil 3D Help topic Sections.

Exercise 1: Creating Sample Lines

In this exercise, you will create a set of sample lines along the alignment.
The sample lines define the stations at which the cross sections are cut, and
also the width of the sections to the left and right of the alignment. A set of
sample lines is stored in a Sample Line Group for the alignment. Each sample
line group has a unique name. Each line within the group also has a unique
name.
For more information, see the AutoCAD Civil 3D Help topic Creating and
Editing Sample Lines and Sections.
