Settings issue rhino 5 64bit

I suppose I accidentally changed a settings but I have no clue where and when.
I do not know how it is called in english therefore I try to describe it and show it with a picture.
Please help me.
the problem: when I select a viewport and move the view, the objects suddenly are displayed in a kind of wireframe instead of normal. On the picture the trange view is the right upper. Please tell me step by step where I can change this setting to normal.

Rightclick in the upperleft cornerpanel. You’ll see the list of display mode options.

I suspect you checked the box for BoundingBox display:

John, THANKS!!!

It’s a handy tool if you have a big file and a display adapter with poor performance.

But very unhandy :grinning: when accidently set and not knowing what you did.

Thanks again for your help.
I was already looking for 3 days how to solve this… :roll_eyes:
