If you’re using the Orchid package you should post this on the project’s github. The author isn’t accurate here and as such support here is somewhat restricted.
archilab has a “ByElementId” Node which allows you to collect elements by their revit IDs.
There is also an out-of-the-box node now for exporting families.
Happy to share my Python code I use in some of my tools I’ve developed at work given it’s been built in so many places/firms.
# Function to close family document
def famUtils_close(family_doc, option_save = True):
# Try to close the document
try:
family_doc.Close(option_save)
return 1
# If we can't, return 0 for tallying
except:
return 0
# Options for saving document
options = DB.SaveAsOptions()
options.OverwriteExistingFile = True
# Typical loop to open, save, close families
for f, p in zip(families, filepaths):
famDoc = doc.EditFamily(f)
famDoc.SaveAs(path, options)
famUtils_close(family_doc, False)
You’ll still need to get the family document(s) and build up the desired path(s), but that’s the core how you can save out families from a project.
You can get families by name using an approach like below:
# Get family documents
families_all = DB.FilteredElementCollector(doc).OfClass(DB.Family).ToElements()
families_names = [f.Name for f in families_all]
# Put your names in here
targetNames = []
# Get the families by name
families_get = []
for t in targetNames:
if t in families_names:
ind = families_names.index(t)
families_get.append(families_all[ind])
else:
pass
# Or you can append None and process it later
In my case I use pyRevit to generate a list of all family names sorted by category in a list view, but Data-Shapes could do this for Dynamo comfortably.
