List shows empty

Revit
1

Hi all,

I wondered why I am getting the list empty. I have checked with length and width parameters and the list shows the values. But when I try to to check with Foundation Thickness parameter, it will show only the list with blank values. It is not showing any of the values. Please let me know the solution for this.

HI
is it type or instance parameter ?

Hi @khuzaimah.ElecEng it is a Type parameter

in this case you have to use Element.Type node before Element.GetParameterValueByName
