Hi Dynamo Community,
I am working on a coordination host project with multiple linked Revit models (5 linked files). I am trying to extract/filter elements (specifically Walls / Murs) from a linked model that are visible within my host file’s active detail section view.
When using standard Dynamo nodes like All Elements of Category in View, it returns an Empty List because standard collectors query the host document database directly and do not evaluate elements inside linked models or translate the view crop box into linked coordinate space.
are these availble as dynamo nodes as well?
is there a way to do this using dynamo nodes?
The Python script which @Mike.Buttery posted can likely be pasted into a Python node and executed directly. Give it a shot and see if it works for you. 
this one? it gives me an error !
That’s the node and the script. Scroll down to line 27 in your Python editor and see what that line indicates.
heres what it says? sorry i dont use python at all , isnt this possible using nodes?
Shifted the conversation over to your new topic as the previous one was already solved and you need to get more specific. Which version of Revit are you in?
revit 2025 , basically i have this section view in host project of multiple linked projects,i want the possibility to extract the linked element (wallas,slabs)that are visible in the host view so ican perform an geometry intersect with the section view outline surface patch so i can create a different 2d pattern , thats what i want exactly . or extract linked rooms of active view!(weather plan , or section!)
There are some packages to get Elements from Links.
I know bimorph and Crumple have some.
yeah but not with the possibility of them filtered by active view!
You’re creating a situation where you’ll be chasing your tail forever with updates to the [architecture/structure/etc.] models, while simultaneously taking a performance hit in the PDFs you make, the views you navigate, and the like. The better option here to use visibility graphics to control the display so you get what you’re after.
That said, there’s valid reasons to get linked objects from a given category in a view so I’m going to whip up a model, link it into another model, and see about a sample graph for you.
Ok thank you mr jacob! but i thought about the visibility solution but it wont work in my case since i want the same walls to have a specific pattern in plans , section and a different pattern in detail sections! i will wait for your solution! thank you so much!
Totally doable - look into view filters. Can even apply different filters to different links in sequence at different scales.
Since you’re in 2025, there isn’t a need for anything custom or Python related.
Built the below with the mindset of wanting to process all elements of the desired categories from all links in the active view.
