RhinoApp.Runscript Invoke from event stream

[lando.schumpich]

Hi, I have problems scripting the -_Import command inside of a plugIn.

I have read through multiple posts with similar issues, the typical solutions where to

• Write a Command and
• Set the CommandStyle to ScriptRunner

my problem is a bit different though:

I run a server that listens for pings on a port and fires events from which i want to to a file import.
Since the file format -(for now)- is .fbx, which can only be imported via script I need to call RhinoApp.Runscript().

The approach i tried

• Create a Command in my PlugIn: XXImportFBX with CommandStyle set to Scriptrunner
• Give the Command a backing field for the FilePath
• Insice the Command call RhinoApp.Runscript($"-_Import \"{path}\" ")
• When I catch an Import event, set the backing field to the appropriate FilePath and call RhinoApp.ExecuteCommand(_doc, "XXImportFBX")

This does not work, the command runs but RhinoApp.RunScript just returns false, which I assume is related to this:

Run a Rhino command from a Plugin

When I just type the command name in the commandline, after the FilePath field has been populated everything works fine, so it seems Rhino prohibits calling commands like I try to do it here.

No errors are thrown at any point, RhinoApp.Runscript() returns false, and RhinoApp.ExecuteCommand() returns Result.Success.

Is there any way I can achieve command execution from a non-command-class?
Since the event stream comes from another application I would rather not have the user run a blocking command inside of rhino which freezes the UI until they click something in said other application.

Since you helped in many other posts related to RhinoApp.Runscript() problems I’m pinging you directly @dale, I hope you don’t mind.

Also the zipped files in this post, seemed like they might also be related to the problem I’m having here, as the UI is also on another thread and can’t be a command class:

RhinoApp.RunScript Not Blocking

Hi Mike, The attached sample seems to work here. Try this: 1.) Build the sample 2.) Launch Rhino and use PlugInManager to install the plug-in. 3.) Put break points in SampleCsModelessTextForm.button1_Click and in SampleCsScriptableCommand.RunCommand. 4.) Run the SampleCsModelessFormCommand command. 5.) Pick the Import button. I’ve included a PDF file to test with. 6.) When your first break point is hit, keep pressing F10 to step over each statement. You will eventually see the break poi…

Thanks in advance,
Lando

Hi @lando.schumpich,

Your import script should be run Rhino’s main UI thread.

RhinoApp.InvokeOnUiThread

Thanks, that works just fine.
