Example of Import/Export Plugin in C#

Hello World,

I am trying to write an import plugin so that Rhino can read directly COLLADA files. Is there any example of an Import/Export plugin in C# so that I know how it could be integrated?

Thanks in advance!


If you use the Visual Studio templates you can instantiate a “skeleton” of a working plug-in. Then only implement what you need to implement.

Where can I find sample code for importing a rhino file while building an import-plugin in C#?

A import plug-in for Rhino will import some file format other than Rhino’s.

What are you trying to do? What file format do you want to import?

Hi Dale. Thanks for your response.
I am trying build a rhino plug-in which will help me import multiple custom rhino template files. Do I need to store the rhino-template files in a different file format?

Rhino already has worksessions:


Is this all you need? If not, please explain further what you want to do and, specifically, why.

I currently have multiple rhino template files which contain a layer and sub-layer setup, display settings, aliases etc. I want to build a plug-in which would give me flexibility on importing either just one or multiple such files to a main rhino file. Ideally this process should run from the rhino-command line which gives you flexibility to import the templates.

In any case, where can I find a solution/example of a C# rhino import-plugin (highlighted part in image below) that is used to import a file format other than rhino’s.



Hi @atharvaranade4,

Generally speaking, the purpose of a file import plug-in is to read some foreign file format into Rhino. You wouldn’t write a file import plug-in to read Rhino files, as it’s already pretty good at doing this.

Perhaps all you need is a general plug-in that has a command this does what you want? A Python script might even do what you want.

How are you storing this template data? Do you have some kind of file that references the template file?

Thanks for your response Dale. I have come very close to coding the import files. Can you help me through this:

I see your first post has been replied to.
