Re: How to retrieve startAngle and endAngle of Arc object

XYZ P45 = new XYZ(Math.Sqrt(2) / 2, Math.Sqrt(2) / 2, 0);

XYZ P60 = new XYZ(0.5, Math.Sqrt(3) / 2, 0);

XYZ P30 = new XYZ(Math.Sqrt(3) / 2, 0.5, 0);

double Angle60To45= P60.AngleTo(P45); // return Pi/12 radian --15 degree

double Angle30To45= P30.AngleTo(P45); // return Pi/12 radian -- 15 degree

I expect to receive Pi/12 with Angle60To45 and -Pi/12 with Angle30To45 how can I do?

Thanks
