In Inkscape, I wish to draw several arcs that are perfectly centred upon each other. The individual arcs need to have different start and end angles. The problem is that when an arc spans less than 360 degrees, the bounding box encompasses only the amount of space taken up by the arc, as opposed to how much space taken if it were a complete 360 degree circle. Therefore, if I should happen to have a bunch of arcs spread over my workspace with different start and end angles, it does not seem possible to centre-align them using the Align and Distribute tools. Similarly, specifying the same X and Y co-ordinates for them simultaneously won't centre them together either.
Can anyone suggest a way around this please? Is it possible, for example, to force Inkscape to retain a 'full' bounding box for an arc as if it were a full circle, to facilitate centre alignment?
