3D model disappeared

[michaela22]

My 3d model disappeared, i've been making apartment building and suddenly in my 3d model view there's just blank page i checked layers and any possible visibility options which are on; i can see the axonometry view but when i switch to perspective there is nothing, any help here please? it's my uni assignment due and i'm hopeless. thanks in advance

When you open the 3D window and the model disappears from view, I assume you have tried the fit to screen command so it zooms to the extent of your model and shows everything? If there’s still nothing you can see there may be a rogue element far away from your main model. Try opening 3D window then fit to screen then select the Arrow tool and then select all. If the info palette changes to show the properties of a selected component there must be model data there and it is then likely to be something placed very far away from the rest of your model.
