Weird indeed, PointAtDist is actually PointAtStation?
ug...not sure I solved it properly / understand it... ran into the same problem with:
PointLocation
Appears any time I change the alignments starting station, or start my alignments with anything but 0+00 these functions have trouble
I think subtracting the pointlocation station from the start station of the alignment solved this one also, but still strange... and without further testing can't verify.
Anyone else familiar with what's going on here can you offer some input? Thanks!!!
