Model disappears when I rotate

as you can see, the whole model disappears when I rotate the camera, and it’s only visible from the top standard view (i have tried the others, that did not help). It just started acting like this randomly in the middle of a session! Does anyone know what might be wrong with it?

nevermind, I found a solution!
for anyone encountering this issue, I fixed it by creating a new viewport :slight_smile:

Hi Vlad, which orientation did you create? Just curious—-Mark

Hello. I think you have a problem with the focal length. Try using the _Zoom and _ZoomLens functions.

I used the NewViewport command, it seems like the default is set to Top.

Select object>Zoom Selected>Rotate View
