Hi Anis,
The attachment is the original ring we were working on, I wanted a way of taking a strip style setting and making it flow onto the ring, what I did was to draw a circle appox. 18mm, then start by dragging the center setting up to it, use the Boolean- diff command and make a curved bottom, then drag the second setting up, using the Beta2 built in rotate tool I turned the setting to the angle I wanted then dragged onto the circle and repeated the Boolean command again, I also did some mirror settings that were in place on the circle to speed up the process, and magic... I got what I wanted without Rhino :)
Regards
Tom
