Not able to get Option bar parameter in Revit

[theshysnail]

Hi all,

As seen in the image, I am not able to get the parameter value of “Diameter” for a pipe fitting. It’s working for the pipe.

Try use parameter name : Nominal Diameter

[theshysnail]

It doesn’t work. There is no parameter named nominal diameter in my model.

The thing is I want to grab the diameter values of both the elements using one parameter name as input.

Revit 2017.2
