Startup commands in scheme?

Good afternoon,

Just wondering if something changed recently with startup commands in the registry? I have a startup_commands registry string in:

HKEY_CURRENT_USER\Software\McNeel\Rhinoceros\6.0\Scheme: MyScheme\Options\GeneralSettings

that does not seem to work anymore on the most recent update (6.5.18149.14421, 5/29/2018). Is there a new method of setting up a startup command for a scheme in Rhino 6? It was working just a few days ago.


Hi @AndrewZ,

Rhino 6 does not store settings and preferences in the Windows Registry. Rather, it saves them to XML files.

RH-46475 Help: Description of the Scheme parameter is out of date

Created this YT issue for updating the help topic.

No, only the location for saving the data is changed.


Thanks for clarifying that @KelvinC. I am working on migrating a project from Rhino 5 to Rhino 6, and in my Rhino 5 project I used that startup_commands reg key to run a command automatically when starting Rhino with my scheme. How would you recommend achieving the same result in Rhino 6?

Hi @AndrewZ,

Of course, the easiest way is to just copy-paste the startup command (Tools > Options > General) between Rhino 5 and Rhino 6. If you’re trying automate this, then you’ll need to edit the setting XML file yourself.

OptionsExport in v5 and OptionsImport in v6 also work for the common settings in the two versions.
