World coordinates of objects How do I see the object's world coordinates. I want to build a scene, view this scene with cameras at different locations and analize what I see. For this purpose, I want to be able to see where my camera and my objects are in the world and how far apart they are. Hence, I need their respective world coordinates and also it might be nice to be able to display the units/meters in the grid.
When I select an object, the location and rotation are all (0,0,0). This must be relative to some starting position of the object but not from the point (0,0,0) in the world.

So:


Where can I see an object's world coordinate?
Can I display units in the grid?
How would I be able to systematically change the position and orientation of the camera with discrete steps in some predefined intervals? Would that be done using animations?


Thanks in advance!
The location of an object is determined by the location of it's Origin.
Most likely all your object origins are at 0,0,0, and not in the centers of your objects.
To move the origins to your objects, select everything (A) and press CtrlShiftAltC> Origin to geometry.

I don't think there is any native way to display units on the grid.

I'm not quite sure what you mean by "systematically", but you could try snapping.
