Hello Dynos,

I want to distinguesh editable and system families

import clr
clr.AddReference('RevitAPI')
from Autodesk.Revit.DB import *
from System.Collections.Generic import *
clr.AddReference("RevitServices")
import RevitServices
from RevitServices.Persistence import DocumentManager
from RevitServices.Transactions import TransactionManager

doc = DocumentManager.Instance.CurrentDBDocument
app = DocumentManager.Instance.CurrentUIApplication.Application

elements = UnwrapElement(IN[0])
result = []

for i in elements:
	for j in i.Parameters:
		p = i.LookupParameter("IsEditable")
		result.append(p)

OUT = result

My code runs pretty well… but without result.

How do i “look” wether a parameter exists in an instance?

Ah okay I think i get it now :slight_smile:

So you want to use that property to filter between system/placeable families?

How about this, @Draxl_Andreas:

elements = UnwrapElement(IN[0])
result = []

for i in elements:
	try:
		type = i.Symbol
		result.append(type)
	except:
		result.append('system family')

OUT = result
