Add Detail Item Line Based

I am trying to add a line based detail item to my Revit model. When I plug it into the detail item I get the error message to use “Add Detail item (Curve), but I don’t see that in the list. Where can I find it? If I use the “Add Component (Curve)”. I get the same error message.

That error / tip is coming from Revit, the Add Detail Item (Curve) is on the feature request pile.

Here is a basic scripted implementation to get you started if that is an option (no element tracking)

ok. Thanks. Yeah element tracking is not an issue at the moment.

That worked, and oh sorry for duplicating a thread. I guess I needed to adjust my search.
