Command line name : PrB_ChiralityConstraint

This command is only useful to advanced users who create custom macros.
This new type of constraint allows you to define the direction of a planar surface, or to define the position of arcs relative to a planar surface.

The constraint is useful to reduce the amount of possible solutions for the geometric solver. It is most frequently used on arcs, cylinders, and plane objects.

Note that this constraint will only have an effect on objects that are fully constrained without any degrees of freedom, and gets lower priority than constraints that explicitly sets the location or direction of a geometry.
