Filter node remaining objects

[Bkarakoyun]

I'm looking for a way to filter objects, it may be a simple question but I'm new to marionettes.

 

Im creating an urban city map for my firm with streets, greenery, buildings etc. The base file for all these parts I download from a database, where they give every part its own name (like: import_streets). I have set up a network which converts these imported objects in a layer from one class to another in the document template my firm uses (so they have the right attributes). Greenery becomes green and roads become grey etc. This goes well, but there are a bunch of objects in the imported file I'd rather delete from the layer im working on. Excess objects like contour lines and region indicating polygons.

 

How do I set up my marionette network so I can filter these specific objects and delete them? I have messed around with the filter node but I'm not quite clear on how it works exactly. I also dont want to delete the classes in case I need them, just in that specific layer I'd like the objects to be gone. Is it possible to input all the objects in the layer into the filter node and make it so it excludes all the objects I want to keep in the layer?

I opted to try it manually, although this is not my favourite way to do it. It's a lot, I'm certain it can be simplified somehow?

 

Also, it does work exactly the way I want to, but once I wrap it, it doesnt. What could be causing this?

I know this is an old question, but do you have the file you were working with still? I have some ideas, but don't have the time to set up a file so starting from yours would be preferred.
