Model not showing up in viewport

Hi,
I have been working on my rhino model and adding various vray elements (ie: lighting, etc.) and suddenly the entire model has disappeared from all viewports. I have tried zooming selected and extents, but it’s still not showing up, however when I select the objects directly from their layers, the command says “13 curves selected…” etc. The model is even appearing as rendered on vray, but it’s not on the actual rhino viewport, hence I can’t edit it.
Regards

Hi Shruti - what happens when you disable V-Ray in the list of plug-ins, restart Rhino and then open that model. Are the objects visible then?
Also, please run the Rhino SystemInfo command and copy-paste the result here.
