Filtering walls


i need help with is !

what are iam missing to connect this to nodes.


I’m not exatly sure what you want to achieve by this graph, but this thread might be of help! :slight_smile:

You need to drive input from Element.Name to FilterByBooleanMask

Also it might be best to rename your Topic, so that it ilustrates your problem :slight_smile:.
This will also help you get more help from other users.

som basic i need to filter duct and pipes out. when i have to get a input from the walls (parameter). later i wil have a excel sheet to change peramenter values and push back to revit.
i can do is. Test.dyn (10.6 KB)

Your dyn can be simplified if you just need to split the wall elements away from the rest of the categories. The grey section I’ve labelled “Filter by Category” can be further reduced by using nodes from packages, e.g. Springnodes or Rhythm
