Video Links: Entering Horizontal Cogo
The Horizontal Cogo Editor is used to enter the horizontal geometry There are 4 types of horizontal cogo entries. Straight, Curve, Spiral, and Compound Spiral. Entered values display in black. Interpolated values display in red.
Station Start |

|
|
Northing |
The northing coordinate of the beginning of the current curve segment. |
|
|
Easting |
The easting coordinate of the beginning of the current curve segment. |
|
|
Arc Length |
