 X end point (diameter value)
 Z end point
 R radius
 I center point absolute—(diameter value)
 K center point absolute
 Q point of intersection (default: Q=0): Specifies the end point if
two solutions are possible (see graphic support window).

„ If you do not program the center, MANUALplus
automatically calculates the possible solutions for the
center and chooses that point as the center which
results in the shortest arc.
„ The direction of rotation of G12/G13 is shown in the
graphic support window.
