In my view port full model is showing, but in camera view and also in render view the full view of model is not showing.
You probably have two different settings for your view port clipping and your rendering camera clipping.
- To check the one in your view port (in Blender 2.8+): press N , select View and you have Clip Start and Clip End.
- To check the one used by your camera select the camera object, go to green Object Data Properties and in the panel Lens.
By default, they do not have the same value
