RE: NEC-LIST: Problem using arcs

Thanks for your help. This works. I said that I was still into
making silly mistakes!

The NEC-2 user guide is not very clear on the specification of the
angles for GA. It states that ANG1 is measured in a left hand
direction from the x axis and I had assumed that the arc continues in
this direction until ANG2 is reached like, for example, Autocad.

Am I right in assuming then that the arc is always drawn from the
smaller to the larger angle? So a 20 degree arc crossing the x axis
would have ANG1 = 350 and ANG2 = 370?

If not, can someone spell out the rules?

Thanks,
