    Default Driving parameter value by using a multiplier factor

    I am building a Flow Meter for a project team and i want to use a Multiplier to control the size of the larger diameter in the family. The Nominal Diameter is set based on doubling the radius via a parameter, i am then using the Nominal Diameter (parameter value) * Multiplier (Parameter value) to generate the Meter Dia (parameter value). in videos i have see on-line i have followed the same steps to validate my formula. the issue is that when i apply the formula i get the "Constraints are not satisfied".

    Does anyone see an issue with my formula and why is this not working (please see attachment)

    The issue is not with your formula but with the geometry that is being constrained by dimensions. I would choose the Remove Constraints button, which should remove the link within one of the dimensions visible in your screenshot. From there you can manually change the dimension to what it should be based on your formula and troubleshoot why the geometry would not flex as desired. I think the problem is with your Meter Dia dimension, since in the screenshot it is 13.97 but your formula is trying to change it to 13.95. Perhaps your geometry is not locked properly to allow for this change.

    Thanks for confirming, i took a break from this yesterday and came back to this yesterday afternoon and saw the same thing. once i removed the constraints of the diameter it started flexing as planned.
