    Great challenge Acorn. I learned from this one. Here is a comparison of my eyeballed one to your correct one.

    Never give up. You will never fail, but you may find a lot of ways that don't work.

    Larry, thank you for your approach.
    I have been trying to avoid math / maths and approximations but as an engineer myself, I appreciate there is always another way.
    Unfortunately, your sums have gone awry as the final rectangle has a side ratio of 1.79::1. We need 1.618::1.

    Earlier, handrawn suggested 1.6::1 was good enough.

    A similar construction to your could map out a ratio of 1.6.
    Thereafter just increase the width by 1% to achieve 1.616::1, accurate to 0.1%.

    My Yellow/Cyan blobs are a 3/5th scaled ruler.

    Marco, it is that.

    Same construction really as Attachment 122666 where I dropped the Blue GR down out of the way and I used one Red square to your two ((1) & (2)). Both have the same underlying math / maths.

    The point of these challenges is to discover Xara constructs that are useful to you.

    Yes the math is the same but this was an attempt to adress the snapping problem, you mentioned there.

    Macro, thank you for the clarification.

    I don't, however, see any snapping that stops on the top right corner.

    You don't need to snap that corner, you can use magnetic alignment. As far as I'm aware, the only snapping issue originally, was the centre of the bottom of your red square, which Marco has solved.

    While drawing the circle (radius creation option) you can snap from the corner of the first to the corner of the second rectangle.
    I thought that the problem in your construction was finding the center of the base of the square, but I now seen that you can easely snap there too, so it was already ok that way...

    Maybe I'm missing something, but I don't see any way to snap to the centre of the base of the square - at least not accurately.

    If you draw the circle and then you move it, you can snap the center of the circle with the center of the square base. After that (selecting the circle tool and holding the shift key) you can resize the circle to hit the square corner. That done, the only thing to do is to resize the square clicking on the right side handle until you reach the snap point at the circle.

    Marco.
