How can one have axis-view? I can't find a single guide/tutorial or any reply to help me out on this one.

So how to reset your view so that you can see the selected and focused object from "axis view" so that you can inspect it from x,y,z axis, and i'm not looking for close enough view. But 100% axis view.(for example behind you is x- and infront of you is x) (focused by numbad ","). So you can see it in "2D", meaning if it's a 3D square (with no self-rotation) you can be able to see only 1 side of it.
Z axis:
Numberpad 7 for Top View
CtrlNumberpad 7for Bottom View
X axis:
 Numpad 3 for Right View.
 CtrlNumpad 3 for Left View.
Y axis:
 Numpad 1  for Front View
CtrlNumpad 1 for Back View
Toggles
Numpad 5 toggles between Orthographic and Perspective view.
For best results, go into File -&gt; User Preferences..., &quot;Interface&quot; tab, and make sure there is a checkmark on on Auto Perspective.  If that isn't set, you may end up with a perspective (instead of orthographic) view along the selected axis.
If your view isn't centered on the selected object, press the Numpad . (period) key.
