How do I keep the centre fixed, please? Hold both shift and control when resizing to (a) scale from the centre, and (b) scale proportionally (keep it circular). You can also use Tile Clones, 1 row x 10 cols, -100% x-shift, -10% x and y scale. That makes a bunch (10) of concentric circles at once, line thickness may also diminish, but that's easy to fix. Finally, if you want to make a set of concentric circles with different arbitrary diameters, it might just be easiest to make them without worrying about keeping them all centred, then select them all and centre them all by using the horizontal and vertical alignment tools. This assumes you might fare best if you key in the diameters, rather than trying to get an exact number with the mouse. Cheers -Terry ```

Hold Shift while drag-resizing. If you add Ctrl, it will even keep aspect ratio :) You can of course also create all the circles, select them and use the Align and Distribute panel to center them. Or try if you get Edit -> Clone -> Create tiled clones to work for you. -- Thorsten Wilms thorwil's design for free software: http://thorwil.wordpress.com/ ```

You may have to move them after. Thanks to all who replied. I went for the horizontal and vertical alignment option in the end and it worked fine. Is it possible to snap the center of a circle to a grid or guide line, rather than the bounding box? Jim ```

Yes it is! Please try this using our prerelease for v0.47, if you're not already using it. Diederik ```
