CounterClock, NoneClock, Clockwise = "clckws", "Cntclck","noneclck", "clckws"ClockSense2 Return the clock sense of U and VClockSense3 Return the clock sense of U, V, WIsCounterCl2 Check if the directed angle from U towards W is counter clockwise, including U==W. Ref is the measure of a full circle, 360 for degrees, 2*Pi for radians, 400 for gonIsCounterCl3 Check if U, V, W form a counterclock wise sequence.
