Here is a link to an image showing an ellips and its properties:
The values of the "Major Point" (which one is that?) are confusing me. The X-value is, as far as I can see, simply the |distance| between the centre point and the endpoint of the smaller radius. I cannot figure out what Y=-37.27 stands for or means. I hope somebody will care to explain that to me, please?
I see this in relation to calculating the area of circles, ellipses and polygons. I found how to find the latter in the Help. But for circles, ellipses, and mixtures of (parts of) these I am afraid we shall have to do some own arithmics??
I dream of finding some means of selecting any contour and see Qcad tell me the area of it. Would that be an illusion?
