Hi,
In Sketchup, you have to use one of the first three commands in the VR Sketch menu (or the first tree buttons in the toolbar). If you use “Upload file to cloud” instead, then you are getting a snapshot, i.e. a read-only cloud copy of your model, and cannot edit it. The point of that command is that you can still view the model at any later time. But for direct connection including editing, choose “Send to VR” or “Collaborative editing”.
We’re always interested in improving the user interface. If that was helpful, could you tell us how we could have made that clearer? Would it have helped with one line of explanation inside the “Upload file to cloud” dialog box?
If you are instead not using Sketchup but our Rhino demo, then indeed that version doesn’t support any editing from VR. VR Sketch is a view-only tool on Rhino. To allow editing for Rhino we would have to support a much larger set of tools; that’s not planned for now.
