This is obviously a fork of RevitPythonShell, bringing an IronPython interpreter to Autodesk Autocad, and it would not be possible without the great work of everyone involved with the RPS project. It's still pretty rough around the edges and provides only basic functionality at this time. I'm sharing my work so far, in the hopes that together we can expand it further.

The CADPythonShell (CPS) ,lets you to write plugins for Autocad in Python, provides you with an interactive shell that lets you see the results of your code as you type it. This is great for exploring the Autocad API.

The biggest limitation is that you can't deploy DLLs with custom scripts at this time and you can't subscribe to events at startup time.

• Interactive IronPython interpreter for exploring the API
  • With syntax highlighting and autocompletion (in the console only)
  • Based on the IronLab project
• Batteries included! (Python standard library is bundled as a resource in the CADRuntime.dll)
• Full access to the .NET framework and the Autocad and Civil3D API
• Configurable "environment" variables that can be used in your scripts
• Save "external scripts" for reuse and start collecting your awesome hacks!
• Run scripts at Autocad or Civil startup

• Download last install stable(msi) from Release
• Use command PythonConsole to open Console or use command PythonShellSetting to open form setting
• See guide install detail at How-to-Install-CadPythonShell

Note : Support for 4 last version(2019-2022) Autocad or Civil 3D. Older versions can be used but will not guarantee the expected performance.

• PythonConsole - Open Python Console
• PythonShellSetting - Open Setting Config Console
• Snoop - Snoop Object In CAd or Civil3d

• Write Console Sample

ed = doc.Editor
ed.WriteMessage("Hello")

• Try create script get Object

import clr
import sys
sys.path.append('C:\Program Files (x86)\IronPython 2.7\Lib')
import os
import math
clr.AddReference('acmgd')
clr.AddReference('acdbmgd')
clr.AddReference('accoremgd')

adoc = Application.DocumentManager.MdiActiveDocument
ed = adoc.Editor
with adoc.LockDocument():
	with adoc.Database as db:
		with db.TransactionManager.StartTransaction() as t:
  			bt = t.GetObject(db.BlockTableId, OpenMode.ForWrite)
  			btr = t.GetObject(bt[BlockTableRecord.ModelSpace], OpenMode.ForWrite)
  			for objectid in btr:
				obj1 = t.GetObject(objectid, OpenMode.ForRead)
				print(obj1)
ed.WriteMessage("Done")
