Boromean Rings

[Acorn]

Starting with three overlapping circles (see https://www.talkgraphics.com/showthr...a-Venn-Diagram), can you construct a set of Boromean Rings?

The key feature is if you remove any one ring to find the other two are not linked.
The follow-up question is how make cuts and re-welds would you need to join three solid rings into a Boromean Ring?



I recall Egg described a method a time back.

Over under over under over under etc.

Thanks Gary, effectively you are cutting and repositioning four shapes.
I suggest it can be done with only two, which is in the spirit of the follow-up question.

There is also a preparation stage - how should you get from a circle with no line width to a circular shape that you have used?

I created a circle, increased the line width, then converted the circle to shape.

Have no idea how to do this any other way. It took me a long time just to get to this stage.

Well if you create the following shape, then get the rotation circle in the right spot you could rotate a duplicate 120, and degrees and again. But I am sure you have a more clever method.

Gary, I was thinking ahead for those users without XDPX. In XWD(P), there are no Convert Line to Shape, Break Shapes, Clipview or even Convert to Editable Shapes options.
