Additional option to the extensions menu

hi everyone,

first of all please excuse me for the grammar, english is not my mother tongue.

My question is:
how can I create an additional option to appear in the extensions menu, which would open an HTML interface?
Just like the Extensions Warehouse opens from SketchUp.

thanks in advance for your help

You do need to be familiar with SketchUp Ruby API, and you must write an Extension.
Welcome! | SketchUp Developer

To get started with writing extensions you can have a look at our examples/tutorials: GitHub - SketchUp/sketchup-ruby-api-tutorials: SketchUp Ruby API Tutorials and Examples

I’d recommend getting familiar with that first before moving on to HtmlDialogs:

This is the simplest way, using your default web-browser:"Plugins").add_item("OpenSomeURL"){UI.openURL("")}

If the URL is ‘local’ there are alternative ways of opening it for PC & MACs - ask if you need that…

That is exacly what i needed.
Thanks a lot!
