7.7.1 Define HZ Alignment
Horizontal alignment consists of the following elements: start point, line, curve and spiral.
To define a horizontal alignment, user should first input the detailed information (Chain, N, E coordinate) of
start point.

Serial number and the amount of present horizontal alignment are displayed on the upper right corner of
the screen.
The element of start point consists of the start chainage and E, N coordinate of start point. Enter these
details, and press [ENT] to display the main line inputting screen.

The screen displays: current chainage, the azimuth angle of the tangent on the chainage, and the function
key of the establishing new line. The system provides four functions: defining line, curve, spiral, and point.
Select a function key, enter the detailed information of the chainage, the alignment elements will be created.
Press [ENT] to calculate the new chainage and azimuth angle automatically and return to the alignment
defining main menu. Now other line type can be defined.
