im was in the modelling room making a model, and i zoomed in, and turned the camera and Boom! I can't find my model now...i know its there...i haven't deleted it...i can only see a blue screen, and im looking into the depths of cyber space.

everything is in place in the assembly room, even the camera is looking direct at my model...what has happened!? is there a way to reset the camera?  and the guide net? help please!

thanks!
