As mentioned earlier, the horizontal alignment can be created several ways.
The easiest way is the point and shoot method, described briefly
below. To create the alignment through COGO (Open Alignment)
see VOL I, Part II, Page 9-34. "Open Alignment"
is one method used if you already know the geometry of the alignment and
simply want to duplicate it with GEOPAK. VOL I, Part
II explains several ways to create the horizontal alignment through COORDINATE
GEOMETRY. A Secret way to create the horizontal alignment,
using COGO, if you know the PI coordinates and other curve/spiral
information, is also explained below.
Copy one of the 2D files listed below from the F:\Resource\Seed
directory to your working directory (name it whatever you want) and get
into it. I would suggest renaming this file something like
PLAN.DGN.
Metric_2D.dgn (metric 2D file)
English_2D.dgn (english 2D file)
