Alignment objects can establish spatial parameters for other objects, including profiles, sections, corridors, intersections, and pipe networks.
If an alignment exists in a site, its geometry interacts with that of other objects in the site, such as parcels and feature lines. For example, an alignment subdivides any parcels it intersects within the site. Any lot lines or feature lines that cross an alignment assume the same elevation at the intersection point. The elevation is set by whichever object is last edited. To prevent an alignment from interacting with other objects in a site, set the site property to <None> or move the alignment to a separate site. For more information, see Alignment and Site Interaction.
