Select All Ducts and Set Each Shared Parameter

[Anonymous]

Hello,

I am new to Revit and the Revit API (as well as C# - though I have taken various OOP courses in Java). My goal for my first add-in is to  select all the ducts in a project and go through each one, modifying a shared parameter value based on connections. I currently have a working add-in that allows me to select one duct - modifying the shared parameter for that single duct. It would be nice if I could get this to work on a large scale. Run the add-in, the add-in selects all the ducts and updates all the shared parameter values one-at-a-time for each duct. Is there a way to accomplish this task?

I have actually gotten this to work using the filters (explained on this page http://wikihelp.autodesk.com/Revit/enu/2014/Help/3665-Developers/0039-Basic_In39/0040-Filterin40/004...) and a pair of nested 'foreach' loops. If anyone runs into a similar issue - as noobie as it is - feel free to shoot me a message and I can show you my code.

Cheers!
