Purge Revit "Line Styles"

Hi Ron,

Than you very much for your post. I was trying to purge some of our line styles here in the office, based on this routine “Excel Roundtrip - Fill Patterns, Line Styles etc.”
However my routine, made with nodes only, was weirdly “deleting” them in a kind of resetting way. It would leave all line styles I was filtering to be removed/deleted/purged, and it would set all their Line Weights and Line Patterns to blank, as well as set their Line Colors to Black.
It would also state that they were deleted, and they would show up as Empty on a second run. To conclude, it was not working. So, thank you again. and Kudos to you.
Below you will find the routine and the images resultant from it.
Kind regards, Haley
