Simple and I should know this, but…When I pull the camera away to far from an object it dissapears. I cant remember how to fix this. I need the object to go from really small to big from the viewpoint of the camera, but when I back the camera up to far the object vanishes. Thanks for your help. It would take me four hours to find the answer on the web.
In the camera panel, at the bottom left there is clip start and end values. Adjusting the clip end should help.
There is also view clipping in the view properties panel, but in your situation I believe it is the camera clipping.
Best of Luck!
