using multiple squares as a layout templet

One of the helpful things I have is over a dozen framing squares. When I need to make repetitive layouts, I will sometimes clamp 2 ,3, 4, or as many as required in which ever layout shape I need. This way I do a layout once then use the squares for the reptations. Here is an example of using 3 squares for an equilateral triangular layout

After marking it is a simple matter to position the rods where the circle and the points of the triangle converge
