I have a file that creates a series of curves between selected elements by using DetailCurve.ByCurve.
Every time I run the file, new curves are created, but those created in the previous run are deleted.
How do I prevent the deletion on each run?
Edit: I have found that by duplicating the lines in Revit (i.e. copying to the same place), I can run the file on other elements. Is there a way I can avoid this duplicating step?
