Creating a simple planar plane with geo nodes?

Support Modeling

I am trying to understand geo nodes.
Found tuts which show how to alter existing objects / geometry.

But is there a way to e.g. create a plane or cube by only using geo nodes?

Have you pressed
grafik?

You will also still need an object, you cannot do this on a collection.

@verty it seems no
I’ve just tried and if you don’t add any GeomNode network, you can’t add any nodes.

So I understand, with geo nodes it is not possible to create totally new geometry in an empty collection, right?

I can’t understand what you’re questioning…
The primitive mesh nodes must be inside a GeomNodes Network that must be attached, at least, to an object.
Some “empty” object can have a GeomNode network attached like Volume or Grease Pencil.
If you want a “fake” empty starting object, you can use a standard plane (or cube or whatever), delete all the vertices and after add a GeomNode network and start adding the nodes you want.
After that, when you completed your network, you could add a fake user to the GeomNode modifier, delete the “fake empty” object and save the file.
In this way you get a file with just the GeomNode network to link or append in another scene, if this is your final goal.

Sorry for unclear question.
I have added a network in my subsequent tests but where still not able to add a e.g. cube.

Your information is a good explanation. I got it, that there has to be a “starting point” in the scene for geo nodes.
