Camera Align with View does not work. Preview does not show Scene View Content

,I started Unity3D practice recently. I am new to game development.

I imported an FBX (created in Blender). I changed the camera (tried with both main camera and the camera part of the imported model) to orthographic. I aligned the view from Camera game object - - Align with View. I do not see the scene view content in camera preview. I further tried Move to View. None of these seem to work for me. Also with perspective camera I had no change in result.

Please guide how to proceed.

Thanks Ishwar

Hard to tell from the angle you provided but it looks like either the far clipping plane value is too low on the camera(try increasing it) or the camera may be inside the object(try pulling it back).

Thanks for the response.
I think i have one possible answer. I installed Unity on very old PC with NVIDIA nForce 430 built in graphics chip. Something is not working in Unity and there is no error message corresponding to that, in latest Unity. Probably, camera is not rendering anything.
I tried on newer machine. It works fine.

All newbies -
Better report (1) the hardware configuration(output of tool like CPU-Z) and also (2) the DirectX version (DxDiag command output). If Unity crashes there is bug report feature. Of course the OS details.
Only after this post queiries here.

I’m having this issue, can anyone please help me out to solve this?!

I cant see anything wrong. Please explain what is wrong in the screenshot.
Your scene view is in orthographic and the game camera is in perspective, maybe thats what’s wrong?
