Automate Rhino5 with IronPython

# The following script is meant to be run inside of IronPython

# start an instance of Rhino

# show Rhino (optional)

Hi Steve,
Thanks for posting this.
I tried if the same would work with F# interactive from VS:

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

but I get this COM error on CreateInstance:
"..class not registered..." REGDB_E_CLASSNOTREG

do you have any idea if this can be fixed?

System.Runtime.InteropServices.COMException (0x80040154): Die COM-Klassenfactory für die Komponente mit CLSID {ECE2F51F-F374-4736-96E7-9DF182CCC178} konnte aufgrund des folgenden Fehlers nicht abgerufen werden: 80040154 Klasse nicht registriert (Ausnahme von HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG)).

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
