There’s not a “powerful” way to do this, per se. If you’re trying to find the center of existing circular objects, you can project them to the current drawing and use the 3-point circle tool to connect their center points.
If you’re trying to generate multiple objects from a center point, you can either draw one of them and use the move tool to create a pattern, or you can draw a polygon from that center point and use that as your ‘construction’ geometry and delete it later…
You can also right click on a straight line and turn it into a mirror line.
Another option is to draw a crosshair and use the offset tool to space the objects you want.
