I have successfully installed the SketchUp Pro (2023) and OpenStudio Application (v3.6.0). Following this, I installed the OpenStudio SketchUp Plug-in which was as per the compatibility matrix provided on OpenStudio Coalition website (

Compatibility doesn't seem an issue here but when I open SketchUp it gives me following prompt:

"Select OpenStudio Root Directory"

Even when I specify the root directory it still throws an error: C:/Ruby/openstudio_modeleditor.rb does not exist.

I am not sure why it says that.

Any solution to this will be appreciated.

Thanks and Regards

What did you enter for "OpenStudio Root Directory"? C:\openstudioapplication-1.6.0 ? Is your OSApp installed there?

Hi Julien, no I entered "C:\openstudio-3.6.0". This is where the OS App is installed but it still gives the same error.

Further, I had installed the Plug-in from "Extension Warehouse" within SketchUp. It installed properly and is showing "Signed" in the "Extension Manager".

I hope this information helps.

Well at least I got rid of one error but it now shows me another error, can't find "" file, when its already there in the specified root directory.

Don't know what's going on behind the scenes.

I know it's confusing, but you must install the OpenStudio Application, not the OpenStudio SDK.

Re-read the wiki at:

Get the 1.6.0 from

The OpenStudio Application 1.6.1 will also include internally the OpenStudio SDK 3.6.1, so no need to install it separately. The OpenStudio Application has - in addition to the Graphical User Inferface - special ruby bindings that the OpenStudio SDK does not have, and that the openstudio-sketchup-plugin needs to work.

Point the OpenStudio Root Directory to C:\openstudioapplication-1.6.0 once you have installed the OpenStudio Application 1.6.0.

Hi Julien,

Thanks for the response. Much appreciated. I already solved the issue, had posted the answer to my own question earlier but apparently it wasn't posted.

I did the same thing as you narrated above, it worked!

While we are at it, just one minor question related to the OpenStudio Application. It also comes with Python Application binding, does it have provision for scripting in Python and implementing the script on the Building Simulation Model. If so, to what extent? Can we test AI based algorithms on the simulation models?

Best, Mubashir

If you want to run code to interact with the E+ simulation (eg: at each timestep), you probably want to look into the EnergyPlus Python:Plugin or EnergyPlus Python (or C) API:
