Native way in grasshopper to ChangeObjectLayer?

I create objects in grasshopper. Is there a native way to tell it what layer to create the object on? Is there a native way to essentially do a ChangeObjectLayer command to move an object created in grasshopper to a layer? I’m wishing for something like a component which takes as input an object (created in grasshopper) and the output is that object on a specified layer (chosen from a list, typed into the component, created ad hoc, etc.).
Please don’t say oh just go to grasshopperdocs,com; that site is entirely confusing as it’s all about plugins/addons and collecting donations, there’s no actual documentation about grasshopper on there. How do you even add a plugin/addon?
Searching Rhino documentation, and even the general web, fails to come up with a straightforward answer that does not involve actual coding, which I’m trying to avoid.
The Rhino tab in my grasshopper UI (Rhino Version 8 SR12 (8.12.24282.7001, 2024-10-08)) looks different than what’s shown on Rhino - Object Attributes in Grasshopper; I don’t have an Object Attributes or Layers sub-tab.
thx

If you don’t need any special layer settings, you can use the Model object component and Cache component to bake geometry and make it available in Rhino.

Can’t see all components? Try to update…

Thanks, that looks promising.

Is there any place that explains, or even documents, how to use the Model Object, Content Cache, or other grasshopper components?

I see that it’s allowed to wire an object, e.g., point, to the Geometry input of a Model Object component. I see that there is a Layer output component, but I see no way to tell it what output layer to use.

I haven’t intuited what exactly “bake” is, and why it seems to be necessary to do some things but not others. I find no documentation about “bake”.

Is there any actual documentation about grasshopper, or do I have to wade through hours of videos and tutorials to eventually stumble across the answers I need?

thanks

Thank you, it does help…sort of. As I mentioned in the post, I don’t see separate component groups for Layer etc. in the Rhinio tab; has the Rhino tab been superseded since Rhino 8 Feature: GH1 Is Now More Than Just Geometry! was published?

Anyhow, after re-reading these docs I think I’m starting to understand, so thanks very much to everyone.

We don’t see what you don’t see. Please post a screenshot if you think something is missing…

Here is a basic example of a GH created geometry placed on a new layer created with GH.

Just wondering if what I have (Rhino Version 8 SR12 (8.12.24282.7001, 2024-10-08)) is correct and up to date.

thx
