Delete unmatched elements

hello everyone, well I’m trying to delete everything that doesn’t have a tag, but I always have to classify the type of family, is there any way to do something that it checks between the parameters if it has any information and then it deletes the that is not in the same pattern?

I CAN DO IT FOR THE WALLS, BUT I CAN’T DO IT FOR PIPE CONNECTIONS

Sure. You have to provide all the categories you’re searching and all the potential parameters. Then you just check to see if any of those parameter values match your filter.

Thanks for the answer!

I’m trying to find the elements but there’s no list.

is there any way to find out what type of element to select?

I don’t quite follow. You have to tell it what elements to look at. When you say “everything” you don’t actually mean all elements without tags, as that would include elements that can’t or wouldn’t be tagged. You have to determine an initial list of categories that could be tagged but aren’t.
