MEPover package/ "Element.AddInsulaton" invalid input

I am trying to write a script for adding insulation on pipes and using MEPover package for this
Unfortunatelly, when i am trying to use Element.AddInsulation node - i cannot, because its yellow and telling me that “input is invalid”

How can it be fixed?

It means the input name/type is invalid. This happened with quite a few custom nodes after a previous update. You can either edit the node and fix it yourself or install the latest version of MEPover.

You can use package DynaMEP

Hey Nick!
Thanks for reply
Using DynaMEP helped to overcome this problem asap.
I was trying to edit the node, but nothing really happened
Is it that hard? Maybe you know where i can find some info on this topic?

Hi Dmitri,
On the red input node change the capital E to a lower case e. Save the custom node after that and it should work again.
Like Nick said you can also update the MEPover package (if that doesn’t work: please let me know , I must have overlooked it then)


Hi T_Pover,
I am also facing a problem with this node.
All the inputs look fine to me. Am I doing anyhting wrong here?

I appreciate the help

Looks fine to me, could you share the revit project for testing?

Sorry for the late reply. it worked fine after updating Revit. thank you again
