COGO Command: Command Descriptions
Table tbCogoCommandData
PURPOSE:
Use this table to enter basic bridge geometry locations. These locations will be used to define nodal boundaries, stringers, floorbeams, truss members, and truck path.
For historical reasons BRIDG includes a near complete COGO package which has many features not needed for 2D data input. Only these 3 commands are commonly used:
COGO Command: STOR (Enter location using coordinates)
COGO Command: OFFSET (Locate a new point from an existing point)
COGO Command: PATH (Define a path. Mostly used for truck path)
