Question:
I found a bug in the new GACP [Gore Area Calculation Program], not a serious one though.
When the program kicks off the profiler app, it calculates 2 PI's at the begin of the grade. These are intended only to give the
engineer the incoming tangent slope at begin station. To do that it uses a GAL function to get the station at 100' behind the
begin station. The problem is this: If the ramp stationing begins at 0+00, the station 100 feet back is negative. Geopak , not
capable of understanding negative stations, returns a positive station value. So, what should be -1+00 comes in as 1+00. That
could be confusing to the engineer.
So far, not sure what to do about it. Except not putting the PI's in there when the begin station is 0+00.
