Hi there. Wondering if there is a way to zoom from the other view than camera view. For an exemple from the top view ? I am working on a little thing and when I go on the top view I only see a little point.

Well, I don't recall B4 to well anymore, but B5 has a pair of tiny little magnifying glasses in the lower right hand corner that work to zoom in and out of the main image. HTH

that's the one... use the zoom and pan tools in the bottom right corner of the screen to navigate the orthogonal views. The zoom in/out buttons will also center the view on a selected object. I know that the spacebar is a shortcut to the pan tool (press & hold, then click & drag), and I think (but am not quite sure) that the + and - keys will zoom in and out in the ortho views.

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.

You can use the keypad +/- keys too, then you don't have to worry about the shift key. :)

you can use the 0,1,2,3,4 keys to quickly switch to different views. The zoom in the top, side, front etc views will automatically center the selected object too.
