I’ve done this multiple times in a couple of plugins, but creating a new plugin, I’m stumped how to add a win form.
I’ve added System.Windows.Forms to the dependencies assemblies, but when I right-click the project name and select “Add”, “new item” doesn’t list windows form as an option.
What additional step or steps am I missing?
Thx. Is there a way to recover from dumb mode, having not checked that box when creating the plugin, or do I have to create a new project and check the box?
You should just create a new project, and check the box. You can then copy/paste the other files into the new project and they should work fine.
As you can see on the left, the default is to create a .Net Core only plugin, by checking the Winform it will add the WindowsForms framework logic (seen on the right).
Thanks, how can I have access to that sub-window to check that box? it only shows the “background” window of your image.
Jorge,
You should download and install the latest Rhino Templates extension for Visual Studio. I also recommend installing Visual Studio Community 2022 if you are still running 2019.
Do you have any resources that might help me understand how to create my own? I really don’t get where to start from…
Hi @Frusciante,
To get started writing plug-ins for Rhino, start here:
For samples to review, including creating dialog boxes and other UI stuff, see the samples repository on GitHub.

Thanks Dale, I’ve seen this posted many times, and actually tried to start from there, but I don’t think it’s that easy, at least for me… I have succesfully tried the “commands” plugins, but never the “forms”.
In other words… “Instructions unclear” 
It really depends on what you are trying to do, because each part may require a different set of learning for you.
Are you building a simple command? Will your command have a UI? Will you use the Toolbar UI and ETO Forms (Rhino’s UI Tech) or something else?
Give me a summary of what you are trying to build and I’ll see if I can steer you in a direction.
I’m trying to make a command, which makes you select a curve (this part I have it covered) … Upon selection, I want a menu (similar to attributes) to trigger, on which I can populate with different options for a given geometry (like sliders, drop down menus, toggles, checkbox, etc…
So, I believe Rhino UI is the kind of solutions I’m looking for.
Appreciate the help if you have any, and if not thanks anyways!
P.D: I’m not really looking for anyone to solve my problems, I’m just trynna find better resources for me to learn. I know the Rhino-developer samples can be very helpful but can sometime be overwhelming when you have no idea what you are looking at.
I’ll try and put together a sample for you this weekend, you can then have an idea of how to proceed to build out such a plugin application.
Man, that would be awesome, thanks a lot!
