Hello all, I am a new Dynamo user so forgive me as I am posting with some little knowledge about dynamo.
Following different posts here, I was able to put together a definition that finds and opens many of Revit central files at the same time from a certain folder. Then using the Rhythm package I was able to Open and Close the files.
But I am unable to execute and set the value of the “Mark” parameter for all the “Wall” elements inside all the opened files.
Please see below my definition and the errors.
Thank you in advance!
