Can't select geometry

I want to delete this greyed out “window” but can’t select it. Tried playing around with hidden geometry but no luck.
Any ideas? :slight_smile:

Share the SketchUp file so we can see exactly what you have set up in the file.

Of course just after I posted this I got it working :sweat_smile:
It seems I had done something strange with groups. Once I selected Edit Group it came back to life and I could delete it.
Lots to learn! Thanks you the response anyway!
