Revit Snippet: Calculate Total Line Lengths with Dynamo

This Revit & Dynamo tutorial will show you how to quickly get the total lengths of any selected lines or all lines of the same category/type. This total is live and will update whenever you add, remove or edit any model or detail lines in the Revit model. While getting total lengths of only selected lines offers flexibility, the ability to obtain total lengths of all lines belonging to the same style also helps you be more productive when this is needed.

thank you!
for some reason "get all line styles" didn't work. It returned "null." But the first method helped me a lot.
