I noticed this Rhino tab inside Grasshopper ribbon in the latest Rhino WIP. What is it?
Hi Tuomas -
Those components make it possible to access more object attributes from the Rhino document and bake Grasshopper geometry with such attributes.
A post with more information is being worked on and will be announced shortly…

Ah, nice! I was a terrible searcher since I didn’t notice that thread. I’ll take a look.
Thanks!
Ah so sad I didn’t notice this. I am finishing smiliar features in my to-be-released plugin. Is it a good time to stop devloping my own? 
However my current work is more focused on blocks. Don’t know if official block support would be added later.
Blocks are on our roadmap but I don’t know when they will be integrated. We’re hoping to get user feedback on which data types should take priority. We definitely don’t want to discourage third party development though. Contributions are always welcome.
@TuomasLehtonen When @wim originally responded, I was still working on the first post for these new tools. However, I’ve now released the first post. You can find out more about these tools here.
Interacting with Rhino is always a huge sector where many third-party plug-ins have been investing.
For example recently eleFront team is working on their next major version.
It’s exciting to see how different plugins and paradigms work together in the future.
My plug-in would work down to Rhino 6.5, hopefully providing extra values to the Rhino community.
Hi! I had a look at the link posted by @AndyPayne and I was wondering if in the meanwhile there have been any updates.
In particular, I’d really like to know if there’s now a live way to modify the objects within Rhino directly from grasshopper.
It’s strange to think that this live-connection thing exists for other plug-ins like archicad-grasshopper but not natively within Rhino…
You can use the new Content Cache component to update existing Rhino objects with Grasshopper data. Meaning, you can reference in a circle, change some of it’s attributes and then use the Content Cache to update the original reference. Is this what you mean by “live-connection thing”? You can read more about the Content Cache here.
