I’m finally getting back to my efforts from this thread: http://dynamobim.org/forums/topic/excel-roundtrip-fill-patterns-line-styles-etc/ and am having an issue with the last piece of Python to write the names back to the objects.

Hi Chad, Which Revit and Dynamo version your using?

2017 (no SP1 installed yet) Dynamo 1.0.0.1118 I just looked and the renaming worked, at least as far as I can tell. There were 2 model patterns with a similar name other than capitalization: Louver & LOUVER - they could have been the culprit as well.

@luupieper I honestly have no idea… If it helps at all, I’m including a graph that I’m pretty sure gets the end result I was looking for in the original post. Manage-FillPatterns-Rename-DeleteByFilter.dyn (34.2 KB)

Thanks a lot, Chad! In the end, I found out that the problem (at least for me) was that I was calling a parameter that has its value defined by another parameter :sweat_smile:

@Chad_Clary Sorry for calling you in a very old post, but by chance do you remember how did you solve this one? I’m kind of having the same problem over here: Modifing light parameters for Lighting Fixtures
