Weird grey box

Any idea what this grey box is? It spontaneously appeared today and appears on multiple computers. It’s immovable and really inconvenient. It’s happened before with another model. Thanks!

Hi k11 - can you post a file that shows this, or send to



Here you go— I moved the model above the grey thing so it was usable, but if you zoom out, you should see it.

Hi k11 - that’s the Groundplane - turn that off via the Groundplane panel (Panels menu)

Any luck?


@k11, did that file originally come from the RH6 WIP? When you export from the WIP to a Rhino 5 format, the GroundPlane is turned on by default.

Yeah—that was it! Thanks!

@andy just mentioning you in case this is something you need to look into

and just referring to my conversation with @BrianJ on the topic:
