Im trying to script drawing of a conical helix in 3D software, and are stuck at the last arc when its not a full 180 degree arc.
I know(calculate) the arc startpoint and endpoint, but how do I find the arc centerpoint?
In illustration, arc centerpoint are x6.252 and y16.796
The software needs only coordinates to do the arc, so i dont use radius either, but i can find the radius by calculating a full 180 degree arc (R14617.447)
draw the arc with :
START pointA_x, pointA_y,
ARC center_x, center_y, pointB_x, pointB_y, cw
How do I calculate centerpoints (x6.252 and y16.796 ) ? do i need arc length?
