Thanks, Daniel, that worked very well except for the grouping thing. AFAICT, the small circle must explicitly slice the big circle. As for the lines, if you slice with a group of lines, only one line actually slices, and it extends itself virtually across and through the shape. Convert the lines to shapes and then group and slice, and you get the results you wanted, but not as a group of shapes. It's a single shape you can break into the right parts. [Sorry if this isn't very clear. I've been interrupted repeatedly, and had to start over twice. Don't have time to go back and clean it up.]

Thanks also for the tip about the contour. That works perfectly for getting the arc out of an ellipse.

All in all, between you and John, it won't take me nearly so long to do the next one. http://www.talkgraphics.com/images/smilies/biggrin.gif
