Calling rhinoscript script files with arguments?


Dear community,

We have created a quite extensive rhinoscript, which is called many times with different parameters. We would like to call this script automatically with the different parameters parsed from a config file.

For now, this config file is read after a Rhino.OpenFileName opens a dialog box. Now, I would like to be able to generate several config files automatically and call my rhinoscript with each time the new config file as an argument. Something like

_-LoadScript MyRvbScriptFileName MyConfigFileName

Is this possible and if yes, how would this work?

Any leads would be highly appreciated.

Kind regards,

LoadScript loads script files.

RunScript runs scripts already loaded into memory (by LoadScript).

If you want to pass an argument to a subroutine, load it and then run it.

Does this help?


Dear Dale,

Many thanks for your suggestions and support so far. I already helped my a lot!
Two additional questions however that I still didn’t figure out:

1. After loading the script, the subroutine I would like to access again is not in the list of subroutines in memory. Only one subroutine of my rvb file seems to be available, while there were 5 subroutines… The other 4 are not visible as explained on but should still be available. However, I was not yet able to access these:

there is a subroutine froMain that takes one argument. However, when trying to call it from C# like:

Rhino.RhinoApp.RunScript("-RunScript froMain 1 “, true)
-RunScript froMain “1” ", true)

Ik keep getting the error message "Wrong number of arguments or invalid property assignment: 'froMain’
While I am sure that froMain is defined and takes 1 argument… So I guess I still missed something. Could you point out what?

2. Objects defined in rhinoscript are still in memory after a run of my script (I can see this when clicking the debug button of the monkey editor when running my script for a second time, before the initialization subroutine is called.
Is there a way to access these variables and objects in memory still in memory in Rhinoscript from C#?

Many thanks in advance,

The RunScript dialog only displays “top-level” procedures - subroutines that do not require arguments. Other procedures are not visible because they require arguments to execute.

Your script sound be surrounded with parentheses:

_-RunScript (froMain "1")

Is there a way to access these variables

Sorry no.

Why do you need access to these variables? If you have a C# plug-in, why are you running scripts?


The reason is legacy. In our company, we wrote quite an extensive script (about 4000 lines of Rhinoscript code) to construct a certain parametrized model. Now, I added a panel that can call this script from C#. Maybe in the long run, the script will be translated completely to C#, but for now I don’t have the time to do that…
