Hi,

I want to find the midpoint on the elliptical arc

I know the following

1 Start point of elliptical arc

2 End point of elliptical arc

3 Center Angle of elliptical arc or Sweep Angle

4 Center point of elliptical arc

5 Major radius of elliptical arc

6 Minor radius of elliptical arc

Angle (in radian) =StartAngle + (CenterAngle / 2)

Where strat angle is the angle from center point to start point in radian

MidX = CenterX +Cos(Angle) * Distance

MidY = CenterY+ Sin(Angle) * Distance

Distance is the Distance from center point to MidPoint on the elliptical arc which is unknown.

Please do help in finding the Distance which is unknown or specify some other approch to do so.

I have tried by substituting the major radius and minor radius as X and Y Distance, but its not giving correct result.

Thanks
