Hello to you all.
I am creating a script that would join all walls from a certain type and all floors of a certain type by selecting one instance and extracting the family type from the selection. However when I run it, some but not all of the floors join the walls. Why is that?
Thank you for your time

@ADG looks like a lacing issue. try set the JoinGeometry node to cross-product. i think the end result should be a list with 20 bools, some true and some false.
Hello! Thank you for answering. I don’t know what cross-product means because I am a noob at Dynamo, could you explain how to do it?
see the “AUTO” at bottom right of that node, right click then look for “Lacing”. there’s should be an option called “cross-product”.
Oh wow that worked! Thank you, you are a genius

Thank you! I will make sure to read that 
If you have time I have also opened a topic that might interest you:
I think the script just needs a few tweaks but it could auto-renumber sheets based on the number of sheets you have in a specific browser category!
