I’m working on content updates and have a couple random old shared parameters in my families and I have no idea which families it is in. Is it possible through Dynamo to query the families and determine if the parameter exists? If so a nudge towards the proper nodes would be ace.

I’ll be going through quite a few more families over the next few months so anything other than manually opening every family would be awesome.

Start with the Primer. [http://dynamoprimer.com/](http://dynamoprimer.com/)

Then look into **Element.Parameters** and “Bakery” Package - **List Shared Parameter GUID’s only** node.  
From there you can built list, determine the family that has these and go from there.

Cheers,
