Input to door parameters from host wall parameter

Hi, It’s first time that I use Dynamo for Revit.
I want to Input to door parameters from host wall parameter.
Please look below.

-Wall has information.
-Wall has many kind of information.

I tried half a day…But I can’t.
Please someone help…
Thank you.!

I might miss here what you want to archieve exactly? You want to write into the door family the host family in this case the Wall?

You want to write it into a certain parameter and which value from the wall you want to read?

Thank you for reply.
I want to input to wall parameter.
Wall Instance parameter have text information.

Thank you.

Then first you need to collect the Wall Host like you did…
Then for the walls you need “Element.GetParameterValueByName” to extract the information from a certain parameter.

And for the doors you need Element.SetParameterValueByName then pick a parameter and the value is the value that you Get from the walls…

Does this make more sence, i will make a little example for you in a minute

Thank you!!!
I could make it!!

Thank you again.
