Any method?

[KenHines]

Is there a straightforward method to ensure that a connection point is precisely positioned at the exact top, bottom, left, or right of a circle?

I don't agree with top left

[wapperdude]

I concur with Yacine.  And Surrogate is on correct path, just needs course adjustment.   

Need 4 connection points:
Top =>       width*0.5, height*1
Right=>     width*1,     height*0.5
Bottom=> width*0.5, height* 0
Left=>       width*0,     height*0.5

Sorry!
I was born left-handed. I was retrained in primary school.
But still, for over 40 years, I sometimes confuse left and right.
