I could use some math help.

[[Ri...]]

(All numbers are metric)
I have a part that is bowed 2.31, it is 1080 long, but measures 1079.54897.
The bow happens to be almost symmetric.
How do I calculate the linear loss?

Sounds like you need the chord length.
sin(Angle A/2)*2*Radius.

This can be problematic - for calculation you need more then just these two numbers. As Clarke wrote - you need R and angle.
All i found was trials - each repetition you are comming closer to result.

SolidWorks denies to work ( radius will be very big ).

Found Hugens derived formula ( don't know if it helps ):

Well we know
M = 1079.54897 (Actual measured value)
C-D = 2.31460 (Actual measured value assumed from "Form")
I think I need to calculate "m".
I wasn't able to create a reliable circle in Calypso, I attempted with the same data 4 times, it resulted in four different diameters.

Maybe try using the chord/height Ratio calculate the Length be linear interpolation? This is found in the machinery handbook. You find it by searching chord length. Based on numbers you posted, your ratio is .002139 which you can used to calculate your length.

"m" is simple trigonometry - pythagoras:

• m^2=d^2+a^2
• m^2=(M/2)^2+(C-D)^2
  m^2=539,774485^2 + 2,31460^2
  m^2=291 356,494657015225 + 5,35737316
  m^2=291 361,852030175225
  m=539,7794475803753914171952577488
