Get all categories to which shared parameter is assigned

[m.shcheblykin]

Hello Dear professionals,

Could you advise a good way how to get all categories that are associated with shared parameters.
I already checked one topic:

Get all categories of a parameter

After looking into this a little bit I’ve been able to get the CategorySet for a given parameter, however I haven’t figured out how to iterate through the list to return the category names. You can however check to see if a category is contained within the set. You can see here I checked to see if three categories were applied to a specific project shared parameter. If you know the categories that should have the parameter applied you can check to confirm them. [image] Here is the python code…

it does not work. Have no idea why.
error :

I need to know which Shared parameters I can delete based on categories list which I expect to get with Dynamo

for i in params:
    shared.append(i.IsShared)

OUT = shared

Hi,

You could use the Get Shared Parameter node from the Genius Loci package.

hello,
thank you for your reply.
The point is that I do not have shared parameters file and only God knows from how many shared parameters file (txt) I got 1600+ shared parameters in the model. I need to find the categories directly from the revit model
