Hi Ruben,
It's probably a bug, and I say probably because you are using ArcCalc
in a more vigorous way than we originally did, which was for static
map images (no zooming) and for arcs less than 180. I would guess
that the trigonometry functions used in ArcCalc are giving
indeterminate answers for direction when the angle is PI or close to
it. The relative orientation of the two points of the line probably
affects the results, too.
Unless you want to work it out, we can add it to the bug list for
review.
Cheers,
Don
