Hi all, I tried searching topics about shared parameters and found out that most of them are “create and add to project” my question is how about removing or deleting unused shared parameters? I’ve experienced working with the project that has the same parameter names. Any idea on how to sort param…

@interactiverendering I was searching and was about to create the same topic but found this. Any update as to a solution? Element.Parameters yields little distinguishable info to determine is used or not. [Capture]

I believe it would be a wicked problem to solve, as how does one tell if a shared parameter is not being used? A parameter such as a boolean could be on/off for example - is it not in use if it is off? The only method I can think of is it to collect all elements, use ‘get parameter value’ and ensur…

Old topic, I know. regarding this, I would like to know how I can filter out allready deleted shared parameters? Actually, if you delete them manually in revit, you will still find them with with Dynamo, there is a ton of duplicates. Would be nice if I could filter all the “deleted” shared parameter…

I had a similar situation. I’ve imported a few families into my project, than, after a few months deleted (replaced with family parameters) their shared parameters. I actually used @GavC ’s Crumple package for that (and Orchid) [DY 2.3 - B7 - shared parameters in family to family parameters_2021-…

Reviving an old thread- same issue today when changing shared project parameters from NUMBER to AREA - and got : [image] the manual solution was use Snoop and look up each shared parameter (See Purge Shared Parameters From a Revit Model | OpenDefinery/Blog ) Then Select by ID and DELETE manually. …

Not sure I follow what you’re after. Can you post an RVT in a new thread (linking here) with a data set to test on? Keep it to one unused shared parameter and one used shared parameter so we can confirm an initial POC.

Not too long ago I had a similar issue and I found that if I just iterated all ParamerElements and did a string equality on the param name I could then delete both and the Shared param would be gone. Now, that doesn’t check usage, but it was much faster than hunting ids in lookup.

This is because behind the scenes the binding remains. I believe amongst other reasons this relates to a parameter being able to remain in project schedules as a field post deletion. A good proof for this is; Add a shared project parameter Detele it from the model In the shared param file, change…

Quick point of clarity - it’s not the bindings that remain, but the definition (which is defined by the shared parameter, which is defined by the GUID not the name). I believe that this is to prevent family data loss as the family elements may still need this data point to not go crazy if you do som…
