Hello- what happens if you type 4View and Enter?


type “NewViewport” in Command line

or like Pascal said, direct type 4View

Nope, doesn’t work

Doesn’t work… is there a way to pin up floating viewport?

try to type “ToggleFloatingViewport”

says “Unable to change floating state for current viewport”

I have try to delete the Viewport like yours

then type “4View”

or use “ToggleFoatingViewport” to pin up.
It works for my Rhino.

Hello - what happens on 4View, anything?


nothing happens with both commands

yep doesn’t work

doesn’t work. nothing appears

Hello - if you have not, please re-boot the machine, and then start up a session of Rhino - does it open correctly?


Nope, doesn’t work. This problem is here for couple days already…

go to windows> add or remove programs then find rhino, left click once on rhino, the hit the modify button… then hit repair and let it go through the repair function. then restart your machine and try it again.
