### f58 Create 3D circular arc with three positions

Description
Creates a circular arc specified by pos1, pos2 and pos3. The arc will turn in counter clocwise direction from pos1 through pos2 and end in pos3. If this is not possible VARKON automatically swaps pos1 with pos3 and lets the arc start in pos3, go through pos2 and end in pos1. In any case the arc turns in counter clockwise direction with a (arclength) parametrisation of t=0 where it starts and t=1 where it ends.
The resulting 3D arc is always placed in the XY-plane of the active coordinate system. If any of the positions are not in this plane they will automatically be projected to Z=0 before the arc is created.
Available in

Comments
If two positions coincide or if all three form a straight line an error is reported.
