> I am trying to set a parameter in my wall types that reads the thickness and material of each layer of the wall construction. I am able to do this for one wall at a time (see attached) but I would like to be able to just hit run and it will go through all my wall type in my project.[image]

Hi All,

There are two ways of getting elements, and the videos are below.

[Dynamo - Get Structural Elements](https://www.youtube.com/watch?v=37xjRVaPDOw&t=7s&ab_channel=BIMTAMIN)

[Dynamo - Get Materials](https://www.youtube.com/watch?v=kq-2j7nszsM&t=4s&ab_channel=BIMTAMIN)

I hope it is helpful!
