Build plug-in with the ScriptEditor


I was wondering if there are any guides on how to build and compile a simple “Hello World” plug-in from a .rhproj with the ScriptEditor.

When I publish the following project I am unable to load the HelloWorld.rhp and execute the command CMDHelloWorld.

Hi @AMG did you see this video by @eirannejad ?

Hi, yes I have seen it. Not sure what I am missing.

Hi @AMG, what happens if you drag & drop the *.yak file instead of the *.rhp file ?


hi @AMG what @clement suggest should work. I’ll ask if loading rhp’s like it can be done on Windows is possible

Using the *.yak works. What is the difference between the .yak and .rhp?

Hei Håvard -

A .yak file is basically a .zip file where the extension has been changed to .yak. It contains / can contain an .rhp file.

I’m trying to export my Grasshopper definitions as a Grasshopper plugin. I’ve followed the video, but I don’t have the GHA file in my output folder as expected.
Thanks for helping,

Someone from MCNEEL could help?

Hi Wim,
do You have some answer to my following question?

Hi Roy -

No, I don’t. @eirannejad probably has more information about this.

@lopez Would you mind sending me your .rhproj file. The screenshot does not tell me much
