how to put dimension to quadrant point of circle.
I put point on circle and try to make considence of it with quadrant point but without success.
Why SW show quadrant points if I can`t use it.
At the same time I can`t select center point of hole in drawing.
Is only way to show sketch of part and to make relation to it. But it is very long way because of absence "find in tree" function in drawing unfortunately.
