Python script to get type name from an element

Revit
1

Hello everyone,

I’m starting learning how to code with python, I need a function in python that given an element return the name of the type.

I’ve tried to use getparameters and parameters but nothing seems working.

This should do it for you…

import clr

clr.AddReference("RevitServices")
import RevitServices
from RevitServices.Persistence import DocumentManager
doc =  DocumentManager.Instance.CurrentDBDocument

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

"""
Ensures input is a list object.
"""
def tolist(obj1):
	if hasattr(obj1,"__iter__"): return obj1
	else: return [obj1]

# The input Elements. We must UnwrapElement here to allow us to use Revit API...
elems = tolist(UnwrapElement(IN[0]))

# An empty array for storing results...
outList = []

# Loop through all given Elements...
for e in elems:
	
	# Get the Element Name...
	eName = e.Name
	
	# Since we are not sure what subclass of Element we will get, we should use something that all Element subclasses will have which is the Element.GetTypeId() method...
	tId = e.GetTypeId()
	
	# If this TypeId is invalid, then we put a null into the outList and skip the rest of the code in this loop...
	if tId == ElementId.InvalidElementId:
		outList.append(None)
		continue
	
	# Here we are getting the ElementType object from the Document...
	t = doc.GetElement(tId)
	
	# Now we get the Name. This is a parameter and we get it like this...
	tName = t.get_Parameter(BuiltInParameter.ALL_MODEL_TYPE_NAME).AsString()
	
	# For completeness, here is the Family Name which we get from ElementType.FamilyName property...
	fName = t.FamilyName
	
	# Put all these name values into an array and put into the outList...
	outList.append([eName, tName, fName])

# Return the outList to the graph...
OUT = outList

This is a bit extra than just the TypeName, but as you are learning I thought I would expand a little. This should work for any Element.

Cheers,
Dan
