In the angle constraint, "Undirected Angle" method, the defined angle does not have directionality, only has the effect of limiting the size. The "Undirected Angle" icon is: A: [img=51x34]1803a1763ead47f.png[/img] B: [img=51x34]1803a17648ef13f.png[/img] C: [img=219x102]1803a176538fbdc.png[/img] D: [img=28x25]1803a1765d58d94.png[/img]
