I am in the process of compiling a parameter driven sprocket.
And before anyone recommends I just download the model from the CBLISS website these items are spreadsheet driven and they conflict with the MRP system interface we are using here.
All my formulas seem to be going nicely until I have to enter the square factor into the formula. [i.e. (d0)^2 or powr ((d0):2)]
It just will not accept syntax function.
I have an idea the problem my lay in the unit types in the equation or the previous equations.
If anyone has some suggestions.
The formula I am trying to achieve is
Hr = sqrt(Fr^2-(1.4ul*DR-0.5ul*PITCH)^2)
Refer to JPG for clearer picture as to where I am coming unstuck.

According to the image you attached, the formula you entered results in a unit mis-match error. See here:
However, if you enter the entire formula that you wrote out in your post (sqrt(Fr^2-(1.4ul*DR-0.5ul*PITCH)^2)), you shouldn't have a problem (as seen in the image in Mick's post). Because the units are being squared and then square-rooted, Inventor won't like the formula until you complete it by closing the square-root function.
