Schedule Ducts by Level

I am just starting to use Dynamo. I thought I would start by creating a script to show me a list of ducts on any given level, so I can schedule duct by level, but I am really struggling. I have tried a couple of different approaches. First I created a list of All Elements at Level but I cannot figure out how to filter out only the ducts. Then I created a list of All Elements of Category DuctCurves, but now I cannot figure out how to filter the list by level. I’m getting very frustrated and would really appreciate any suggestions. Thank you.

Hi Brad,

Don’t get frustrated. You need to use “GroupByFunction” to filter your Duct curves by level. See Below graph.

Good Luck & Happy New Year :)

Thank you KULKUL. That makes perfect since, but now how do I get the list data to show in my Revit schedule?

Is there a good resource that details how to use all of the Dynamo nodes? I cannot find much information on the web.
