I was looking at another thread, and in trying to solve it for the poster, discovered it is rather difficult to form an array of circles of a given diameter to meet at just their tangents.

Yes, I’m aware that SketchUp doesn’t have true circles, so don’t preach that to me, please.

The diameter doesn’t really matter. So let’s say the circles have a 3’ diameter. I would like to create an array of 15, 12, 8 and 5 circles that only meet at their tangent points.

Every solution I’ve come up with has overlaps.

Thanks

Chris
