[[JOSMImage(aligncircle,middle,link=,48,margin-right=20)]] ''Keyboard shortcut:'' **`O`**

**Move the selected nodes into a regular polygon.** \\
At least four nodes or a closed way with at least four nodes need to be selected for the default behaviour. 

There are also some special cases:
 * When one node, part of a way, and this way are selected, then make a regular polygon
 * When one closed way and one separate node is selected, set center to position of that node.
 * When one more node, part of the way, is selected, set the radius equal to the distance between the two selected nodes.
 * When multiple ways are selected and they are connected to create a ring, align nodes by first computing an average center and by preserving relative angles of interconnection (e.g. of roads connecting to a roundabout) when regularizing the radius, and redistribute the other nodes in each arc.
 * When multiple ways are selected and they are not connected in a ring, then each of the selected closed ways will be circularized.
