Python programming in autocad

[Oliver_C3D]

Can I write to the AutoCAD program or extension with Python?
If you can provide a tutorial or reference file in this case?

Hi,

You can use the pyautocad library with the AutoCAD COM API or IronPython with the AutoCAD .NET API (and also the COM API).

In addition to what @_gile said, there's the comtypes package.
If you understand AutoCAD's object model, you can invoke almost every method and fetch almost every value.
However, the main downside of comtypes is that you need to supply all arguments to every method you invoke, even the optional ones need to be explicitly supplied.

To catch the feeling of how it is "simple in theory" to connect to AutoCAD with python you can see the included code within this question of mine about an issue.
Postcommand doesn't read AutoLisp expression [Python 2.7 & AutoCAD 2016 Windows]

hello serag.hassouna ,

I wanted to ask you for more detailed instructions, on how can I receive specific measurement from AutoCAD (maybe student addition) to a python program:)))

thank you for your help!

You can use project cadpythonshell, An IronPython console for Autocad and Civil 3d API, include full snoop Database to explore CAD.
