Filtering out only the walls from All Elements at Level node

Revit
1

hello,

I’m using Levels -> All Elements at Level node to get all the objects on certain level only.
Is there a way to filter out only the walls out of the entire list?

Thanks!

You can use the node from archilab or go the OOTB route.

Sickkkkkk thank you for the fast response.
I def prefer archilab route. I am planning to have a somewhat dense script. do you think archilab route will be faster? thanks!

Yes, I believe that it would be a little faster than the OOTB route.
Also, in case if you are planning to reduce your package dependency, you can use this code by Konrad from GeniusLoci.
