Can you plug those nodes into the GET node and show the output pls.

Eg, what is coming out of here?

That’s the SET node… not the GET node… What happens when you plug in the GET node. Element.GetParameterValueByName << this one…

26

i can’t figure out how to do the link :frowning:

27

and where var… should go?

when you click these boxes you can link a parameter, so the value of “MyWidth” will be the same for Extrusion end. with the dynamo script you manipulate the "MyWidth paramer.

but i need both of them for my task, and at the same time too, and it becomes gray once i link it

OK… So that element isn’t recognising 'Mywidth" because it’s a type parameter.

Try this node from Rhythm

33

is there a way to make it a type parameter?

34

thank you for bringing it down, because i can’t find by search bar this exact node, where is it located, why i haven’t found it?

35

If you’ve not got Rhythm you can do this.

It doesn’t ‘make’ the element a type parameter. It finds the type of that element. The element by itself is an instance.

Although I’d suggest getting some packages installed.

What version of Revit are you in?

It would help you a LOT to stop what you’re up to for a bit, and go through the Dynamo Primer from end to end.

It would help others to help you if you posted your .rvt file so we are all on the same page. Three others have tried to help but it isn’t clear if your are running Dynamo in the project environment or the family environment; if the parameter is a type parameter or an instance parameter; if the expected value is a string of a double or an integer; etc.

Try Element.ElementType - which you were using before.

I pin my rfa file, i hope someone will have a min to take a glance of what’s going on
