There are a couple of things.
All the paths are drawn clockwise. If you run Union on each ring before executing Difference you will get a different result. Not necessrilt better!
If however you break apart the each ring and reverse the direction of one component path from each pair, and then combine, before running Difference you will I think get the result you are looking for.

Thanks C R.
That was the first thing I thought too, at first. The bottom object must have a stroke. But as I said, they are both filled with no stroke.
Here's link to SVG file: http://inkscapecommunity.com/jd/imgs/diff-diff.svg . It has the rings already duplicated. So to reproduce, select the top green and top gold rings, and do Difference.
Thanks again :-) brynn

Could not duplicate the error, however if you have a stroke applied to your shapes that is the same colour as your fill, that may explain what we are seeing here. :)
Boolean shape ops are done to fills only, and do not take into account line thickness on the resulting paths (this is intentional).

Hi Friends, It seems like I should know the answer to this. But I don't recall hearing about it. Starting with these 2 rings, which have fill and no stroke: http://inkscapecommunity.com/jd/ss/diff1.png I duplicate both, and then Difference. At 100% zoom they look ok. But zoom in (in this case, all the way, for best view) and you can see that the Difference wasn't correct. http://inkscapecommunity.com/jd/ss/diff2.png It's not a huge amount, but I would expect there shouldn't be any difference at all. This on Windows 7, 64-bit, sp1, Inkscape 0.91, 32-bit, exe installer. Is that a bug? Or is there some reason it's expected not to be precise?
Thanks for your help :-) brynn
