Bases: CommandToken
Wrapper for G75 token.
In multi quadrant mode the arc is allowed to extend over more than 90°.
To avoid ambiguity between 0° and 360° arcs the following relation must hold:
0° < A ≤360°, where A is the arc angle
If the start point of the arc is equal to the
end point, the arc is a full circle of 360°.
0° ≤A ≤90°, where A is the arc angle
angleIf the start point of the arc is equal to the end point, the arc has length
zero, i.e. it covers 0°. A separate operation is required for each quadrant. A
minimum of four operations is required for a full circle.
