Short description of error
I might be wrong here but I was under the impression that we're now able to create a mesh instance and be able to modify it with geometry nodes, without a mesh to modify preexisting, out of 'nothing' so to speak.
If I delete the default cube to have an empty project I can't add any nodes to i.e. instance a mesh and take it from there. Without a mesh the "+New" button above the node grid doesn't work. Nor do any of the options in the "Add" menu.

Exact steps for others to reproduce the error

  • open new general project
  • delete default cube
  • switch to geometry nodes workspace
  • check nodegrid workspace "+New" button and workspace menu entries for usability (ie Add) - all choices should be disabled so

If I delete the default cube to have an meshless project I can't add any nodes with the workspace menus to instance a mesh and take it from there. Without a mesh pre-existing (ie default cube) the "+New" button above the node grid doesn't work, nor do any of the options in the "Add" menu that could potentially instance a mesh out of nothing but nodes and store the node tree within its instance (and possibly a resulting new mesh line in the outliner for the instance), no?

Thanks for the report. Geometry nodes is a modifier used to change the geometry of the Mesh and curve with the help of nodes.

So without an object in viewport, it is not possible to add a GN modifier. (this make sense for me)

This is not a bug so I am closing this report. But feel free to reopen if this is just misunderstanding from my side.
