Based on a feature request for a "concentric circles" tool, I've experimented a bit with the Spiral tool which is capable of creating concetric circles in the linear and decaying mode with Arc Angle = 360°, albeit all aligned to one side. To center the circles subsequently: convert to curves Layer → Geometry → Divide Layer → Alignment → Align Center Optionally, if you need rectangles rather than circles, select all nodes of the converted circles and convert them
