In AutoCAD Civil 3D, you create alignments as objects.
Use the Prospector and Settings tabs to manage alignments in Toolspace.
Alignments are listed in either the Alignments collection or a Site collection in the Prospector tab. From these collections, you can change alignment properties, generate reports, and export LandXML. See Alignment Collection (Prospector Tab) for more information.
Use the Settings tab in Toolspace to manage the details of alignment object styles, label and table styles, and command settings.
Control the visual appearance of alignment components and labels through styles. You can create specific styles to use in the various phases of a project. For more information, see Alignment Styles.
When you create an alignment, you specify a style for the alignment object and styles for the alignment labels. In the Alignment Labels dialog box, you can create groups of styles for alignment labels, and then save those labels as a label set to use with other alignments.
Use station equations to change station-distance references at any point without physically changing the geometry of the alignment.
