The 'Sense' parameter of 'GC_MakeArcOfCircle' does not seem to be operational?

[frankpian]

I endeavored to set 'Sense' as both true and false, yet the outcomes appeared to be identical in both instances.

gp_Pnt p1 (0, 0, 0);
gp_Pnt p2(2, 2, 0);
gp_Pnt center(2, 0, 0);
gp_Circ circ(gp_Ax2(center, gp_Dir(0, 0, 1)), 2);
gp_Circ circ2(gp_Ax2(center, gp_Dir(0, 0, 1)), 3);

Handle(Geom_TrimmedCurve) anArcOfCircle = GC_MakeArcOfCircle (circ, p1, p2, true);
Handle(Geom_TrimmedCurve) anArcOfCircle2 = GC_MakeArcOfCircle(circ2, p1, p2, false);

That's all fine, the meaning of this parameter is just different: it is the geometric orientation of the parameterization:



You should rather change the order of p1 and p2 arguments to make the smaller arc:

@Quaoar Thanks for explaining.
