Mass_Level Filter (BoolMask)

[jkim]

It seems easy enough, but cannot get this Dynamo to get parameter value (“Level”) to show up correctly… “Level.Name” does not seem to be working…what am I missing?

I am trying to get the names of Level for the Mass placed in Revit Project… and furthermore Filter them by level…

thanks in advance!

hi @jkim

please check the first entry of your list of Levels (element 0 of the list) , it is empty that is why you are encountering an error/warning. remove all the Null and empty entries and you will be fine.

Hi @jkim

Here is another possible way to filter regardless if the list contains empty or nulls:
