COGO Command: BIAS

This version of Steel BRIDG requires that the truck path be at Y=0. Some older BDF files that were translated from the older 3D program use a Y coordinate that is not 0. So that all the data need not be re-entered and re-calculated, a bias can be applied to the input data.

Command is:

Command	X-bias	Y-bias	Z-bias ()
BIAS	0	39.85	0

In the following example if this bridge, 305-10, which was converted from an older version of BRIDG, does not use the bias command, and has set the truck (stringers) at Y=39.85 feet, the program gets very confused and will not calculate the truck path correctly.
