Need to alias the AutoCAD Application and import the DocumentCollectionExtension

Hi … I have seen this in many examples … but I get … error …
No module named Autodesk

import sys
import clr

clr.AddReference('AcMgd')
clr.AddReference('AcCoreMgd')
clr.AddReference('AcDbMgd')

import Autodesk.AutoCAD.ApplicationServices.Application as acapp

from Autodesk.AutoCAD.Runtime import *
from Autodesk.AutoCAD.ApplicationServices import *
from Autodesk.AutoCAD.DatabaseServices import *
from Autodesk.AutoCAD.Geometry import *

import Autodesk.AutoCAD.ApplicationServices.DocumentCollectionExtension
2

Try adding this line to your code

import Autodesk

3

It could be between IronPython and CPython, however Application is a class, it is already loaded with

from Autodesk.AutoCAD.ApplicationServices import *

You can alias like this

from Autodesk.AutoCAD.ApplicationServices import Application as acapp

Further the DocumentCollectionExtension class is already loaded from ApplicationServices as well, so unless you need to alias you can use it directly
