Curve.RemoveDuplicates
Removes duplicates from a list of Curves. Dynamo Curves, Revit Model or Detail Lines are all supported. Revit Curves can be deleted from the Document. Input LineStyle names to retain curves of that style.

LineStyle list are iterated until a match is found. If no matches are found, first-in first-out rules apply. To simplify model element selection in Revit, heterogeneous lists (any element type) can be input as the list is filtered before processing.
