When I run the ulp on an in-progress, 2 layer board design (Eagle 6.6) it returns an error:
Invalid argument in call to 'asin(1.244)'
Any ideas on what might cause this would be appreciated.
Does the board need to be DRC error free for the ULP to operate correctly?
It would be helpful to hear from somebody with definitive experience on this.
PS - Having resolved all DRC errors, the exception still occurs.
A bit stuck now. Can't think how to progress without gradually picking apart the board to try to get it to a state where the ULP works, which it did when the board was simpler.
