Automate Rhino5 with IronPython

gistfile1.py

# The following script is meant to be run inside of IronPython
# It demonstrates how to automate Rhino from a script
import System

# start an instance of Rhino
t = System.Type.GetTypeFromProgID("Rhino5.Application")
rhino = System.Activator.CreateInstance(t)

# show Rhino (optional)
rhino.Visible = True
# run your script or a bunch of scripts
rhino.RunScript("!-_RunPythonScript myscript.py", 1)

# shut down rhino
System.Runtime.InteropServices.Marshal.FinalReleaseComObject(rhino)

probably it is a permission problem:

Hi Goswin,

let t = System.Type.GetTypeFromProgID("Rhino5.Application")
let rhino = System.Activator.CreateInstance(t)

works for me and gives me a System.__ComObject

I didn't try to go further
