Where is SymbolLine.ByCurve Node?

There is a model line by curve and a detail line by curve node. But I can’t find a Symbol Line by curve node.

For context, I am trying to convert CAD imports in a Family document to Symbol lines so they don’t show in 3D views.

Have you tried using a detail curve? I believe they’re the same in this context.

Detail Curve doesn’t work, It returns null. I think the geometry is handle differently internally between Model documents and Family documents.

If that’s the case you’ll probably have to go through the API. I found the SymbolicCurve members but no creation method at first glance.

I found them in the familyItemFactoryMethods, But I’m really not sure how to go about using the methods in a python script. Hopefully someone could give me an example to go off of?
