Parameters

Integers
  ITG (I-1) - Tag number assigned to all segments of the wire arc.
  NS (I-2) - Number of segments intowhich the arc will be divided.
Decimal Numbers
  RADA (F1) - Arc raduis (center is the origin and the axis is the y axis.
  ANG1 (F2) - Angle of first end of the arc measured from the x axis in a left-hand direction about the y axis (degrees).
  ANG2 (F3) - Angle of the second end of the arc.
  RAD (F4) - Wire radius.

Notes:
- The segments generated by GA form a section of polygon inscribed within the arc.
- If an arc in a different position or orientation is desired the segments may be moved with a GM card.
- Use of GA to form a circle will not result in symmetry being used in the calculation. It is a good way to form the beginning of the circle, to be completed by GR, however.
