Can some help me out with this I am wondering why the set parameter node is not working…?
Can you confirm the dataset is all detail lines? An Object.Type node and a list unique items node will do that fairly easily.
Are any of the detail curves part of a group or in a link by chance?
Also try passing the elements into an Element.Parameters node, then a Parameter.Name node, and then a List.ContainsItem node where “Line Style” is the desired item (make sure levels are properly enabled on the List.ContainsItem node).
