Hi Mark. I have been working on this during the weekend. I already consulted the site you suggested
and I was able to unwrap the elements as you indicated, with a simple additional python node:
code would be:
import clr
Import ToDSType(bool) extension method
clr.AddReference(“RevitNodes”)
import Revit
clr.ImportExtensions(Revit.Elements)
wrappedElement = IN[0]
unwrappedElement = UnwrapElement( wrappedElement )
OUT = unwrappedElement
so that does give me the extrusions I am after, directly from background family documents, however, when it comes to associating shared parameters to those, it is proving difficult, I am trying to use the code in this thread, but it’s written for a different workflow (working in the current document as opposed to background ones)
anyway, I think I am violating the forum rules, I probably should follow up with a new topic, I appreciate your help!
Best regards
