Purely a FYI post but I just discovered that =POWER() is a function that can be used in Dynamic Components. Neat. (Originally said undocumented, but it is)
Want to create a golden ratio rectangle from a known AREA? set LenX to
=SQRT(AREA*power(((1+sqrt(5))/2),3))/((1+SQRT(5))/2)
and LenY to
=SQRT(AREA*power(((1+sqrt(5))/2),3))/power(((1+SQRT(5))/2),2)
Why would you want to do this? I dunno, maybe you are space planning and you are obsessive compulsive about the golden ratio. Attached is a DC that uses the above. Enter a known SF value and hit apply to see it in action. I made this first with the constrained length but got a little carried away with "what if?"s.
