Edit Alignments
The Edit Alignments screen is used to create and edit alignments,
which can then be used with routines such as Offset Staking, Offset
Points, Offset Lines and Road Layout.
Alignments are used to describe all of the horizontal and vertical
details of a road’s centerline. An alignment does not use existing
points to define any particular locations on the alignment, although a
point can be used to anchor the starting location, which is the same
location for both the horizontal and vertical parts of the alignment.
Any location on an alignment where a change occurs is called a node.
An alignment can contain straight sections, grades, horizontal,
vertical, and spiral curves. The horizontal and vertical portions of an
alignment are defined separately and independently, but they are
both combined within the software to create a single alignment with
horizontal and vertical characteristics.
