Sounds like you need to zoom in. Get in your top view. Hold down the shift Key and press the plus key on the top row of your keyboard after all the numbers. The window will zoom in steps. If the first zoom is not enough press + again until you can see enough detail. To reverse and zoom out just press the minus key next to the plus. You don't have to hold the shift for it since it's on the bottom of the key. If you click and select an object in a camera view then shift to a front, side, top, view and zoom the field shifts to center that object in the view.
