Create Sectors from Concentric Circles?
I would like to divide an arbitrary number of concentric circle objects into an arbitrary number of individual sectors. For lack of a better term, I want to create a "dartboard" where each section becomes an independent object or path. For example, the attached image below shows 2 concentric circle objects with 4 crosshairs lines (excuse the off centered lines please). From this I would like to generate 16 objects or sectors. Thanks.

Re: Create Sectors from Concentric Circles?
I think you can use Clone->Create Tiled Clones and set Rows to 6, Shift Y to -100 and Rotation to 45°.
I did it and here's the result. I hope this help you!

Re: Create Sectors from Concentric Circles?
Thanks for the quick reply Megasoft78. For my requirements, I need to see 16 objects (not counting the crosshairs). Instead from your results, dragging the select box around the 3 circles shows just that… 3 ellipses. I am trying to create 16 individually editable sectors or paths. I did use Create Clone Tiles to create my original concentric circles, but am by no means a power user. Did I miss something here from your results? Thanks.

Re: Create Sectors from Concentric Circles?
Hi,
I'm sorry I miss that. I think you can use Cut Path with a rectangle.
Check the boolean operations. I'll try to do it for you!

Re: Create Sectors from Concentric Circles?
I'd probably use the boolean tools to get radiating pie slices, then clone or duplicate those into a circle.
Have a nice day.

Hi,
I did it creating the slices first and use tiled clones.
Here's the example:

Re: Create Sectors from Concentric Circles?
Great Megasoft78, looks good. Before I look at your solution (thanks)...I tried simply doing a path cut to get quarters… can anyone say why my cuts are not clean/perpendicular? In the case below the cut shape is a square…

Re: Create Sectors from Concentric Circles?
Here's how I would cut a ring (green) with a difference operation (blue shape cuts the green).

(I duplicated the green cut piece and placed it over the blue cutting shape to show geometry match.)

Re: Create Sectors from Concentric Circles?
I wouldn't use booleans for accuracy reason.
Instead, draw octogons with the * tool,
convert objects to paths (Shift+Ctrl+C),
select nodes and set them to smooth ones.
Once having four concentric circular paths drawn that way,
select every second path, reverse direction,
select all four paths and combine them together (Ctrl+K).
Then the rest is just duplicating the object (Ctrl+D)
and unconnecting-connecting nodes with the node editor tool here and there.
Seems you drew paths with given strokes and no fill (though booleans would turn them closed paths?),
that has such rendering issue.
