Hello I have a problem using this node, as you can see I’ve used the list of elements in ‘‘list’’ and the list of bools in ‘‘mask’’ but it gave me an error or null. Can someone understand the problem?
Hi @cayon9Q4CS ,
You most probably have null values outputting from your < node if the value of the “Altura desconcenada” parameter is empty/ not a number, I recommend first filtering out all the walls which do not have a “System.Double” type. You can do this using the object.type node to get the type of the value and then using an == node together with a string containing System.Double and two boolmask filters, respectively for the walls and values.

Yes, you are right I had some null values, thank you!
