Create Line, Two Point

I have a question that I am doing wrong in the python code to be able to create a line, I know there are nodes for this I am just trying to understand a little python and I would like to know what the error is

            end = AeccPoint3d(end_point.X, end_point.Y, end_point.Z)
            line = AeccLine(start, end)
            ms.AppendEntity(line)

    return line

@Christhian ,

you need transactions! and the right syntex look at this…

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 List

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

#Preparing input from dynamo to revit
element = UnwrapElement(IN[0])

#Do some action in a Transaction
TransactionManager.Instance.EnsureInTransaction(doc)
#create something!
TransactionManager.Instance.TransactionTaskDone()

OUT = element

Hi @Christhian
Can you look at this
