Ungrouping & Purging All Families in a Model

Revit
16

I found some time to take a look at the reloading:

The IFamilyLoadOptions implemented in python:

class FamilyOption(IFamilyLoadOptions):
	def OnFamilyFound(self,familyInUse,overwriteParameterValues):
		overwriteParameterValues = True
		return True
		
	def OnSharedFamilyFound(self, sharedFamily, familyInUse, FamilySource, overwriteParameterValues):
		return True

Here is the call of the LoadFamily method call on the familydocument:

famdoc.LoadFamily(doc, FamilyOption())

@luisa Do you want to test the script? It doesn’t purge anything, because that has to be done manually. There is no API call to the purge command in Revit.

For anyone that might be interested,.the complete python script:

import clr

clr.AddReference('RevitAPI')
from Autodesk.Revit.DB import *
from Autodesk.Revit.DB.Structure import *

clr.AddReference('RevitAPIUI')
from Autodesk.Revit.UI import *

clr.AddReference('System')
from System.Collections.Generic import *

clr.AddReference('RevitNodes')
import Revit
clr.ImportExtensions(Revit.GeometryConversion)
clr.ImportExtensions(Revit.Elements)

clr.AddReference('RevitServices')
import RevitServices
from RevitServices.Persistence import DocumentManager
from RevitServices.Transactions import TransactionManager

doc = DocumentManager.Instance.CurrentDBDocument
uidoc=DocumentManager.Instance.CurrentUIApplication.ActiveUIDocument

class FamilyOption(IFamilyLoadOptions):
	def OnFamilyFound(self,familyInUse,overwriteParameterValues):
		overwriteParameterValues = True
		return True
		
	def OnSharedFamilyFound(self, sharedFamily, familyInUse, FamilySource, overwriteParameterValues):
		return True
		
#Preparing input from dynamo to revit
families = UnwrapElement(IN[0])

for f in families:
	famdoc = doc.EditFamily(f)
	fec = FilteredElementCollector(famdoc).OfCategory(BuiltInCategory.OST_IOSModelGroups).WhereElementIsNotElementType()
	if fec.FirstElement() is not None:
		groups = fec.ToElements()

		TransactionManager.Instance.EnsureInTransaction(famdoc)
		[g.UngroupMembers() for g in groups]
		TransactionManager.Instance.TransactionTaskDone()
		TransactionManager.Instance.ForceCloseTransaction()
		
		TransactionManager.Instance.EnsureInTransaction(doc)
		famdoc.LoadFamily(doc, FamilyOption())
		TransactionManager.Instance.TransactionTaskDone()
		TransactionManager.Instance.ForceCloseTransaction()
		
		#famdoc.SaveAs(path +"\\" + e.Name + ".rfa")
