I am moving very large circles in Inkscape, snapping the centers to nodes on another shape (see links below). I have to fish around with the circle to get the snap guide to appear. I have marked the arbitrary shape with markers, so I tried that for the circles, but the markers appear on the perimeter - not the center. When the circle is very large, it is very difficult. With many nodes, it is also difficult to move the pointer to get one node and not another. I am also not sure how I ought to set the node snap weight yet.
