Struggling with F root, Ddim 2nd, A root, Dm 1st and back to F root!?

I assume you were having trouble with the Ddim (can borrow this from Dorian) and A (use the “V of” option to get this).

If logical deduction and trial and error don’t work for me, I find the chart that someone posted at Symmetric visualization of harmony very useful. If you spend some time figuring out how it works, it is a great timesaver.
