Objects are not visible in Scene Window

The artist exported 3D model to .fbx file. When I imported the model in unity, I couldn’t see anything in the scene window. It seemed the model was very small or invisible. I could not even see the camera.

select the .fbx in project section and check it in preview of inspector . if u see it . u must select the model in Hierarchy section and click in editor window . now press F key to focus on your model .
