Can't use dimension with sqrt()
It's a units thing. Fusion is very literal regarding units. If you take the square root of "9 mm", the actual value would be 3 sqrt(mm). So, you have to do some units gymnastics: "sqrt (d2/1 mm) * 1mm".

I think the help is wrong, it states any for the units but a quick test shows it only works with unitless so you need something like sqrt(d1/1mm)

@jeff_strater thanks for the clarification, still not sure I understand you answer though. Can sqrt() be used without canceling the units?

Hi @HughesTooling,
No, unfortunately, sqrt() is specified to be a "unitless" method. So, you do have to cancel out the units for it to work. Just like round(), etc.
