Glossary
 Units of measure:
 The units of measure used when defining a bolt circle hole list must all be of the
same type, for example: all in inches or all in millimetres.
 Hole diameter:
 The diameter of the holes that are equally distributed around the bolt circle diameter
 Bolt circle diameter:
 the diameter of the circle on which the holes will be evenly distributed.
 Start angle:
 The 0° angle is to the right in the "X" axis and aligned with the center of
the bolt circle in the "Y" axis. The angle is described as...
  A positive angle is counterclockwise
  A negative angle is clockwise. ex:45° = 315°
 Angle units

360° = 21,600 minutes = 1,296,000 seconds = 6.2832 radians = full circle

1° (1 degree) = 60 minutes = 3,600 seconds = 0.0175 radian

0°1' (1 minute of a degree) = .016
degree = 60 seconds = .000298 radian

0°0'1" (1 second of a degree) = .00027
degree = .0000048 radian
