if I create a primitive theres no difference between both
the primitive has no real Center this way
I would like to have a real Center in my primitives
if you create a null its real centered to 0/0/0

    I am not certain what you mean?

    A primitive does have a centre, and you can move that centre point using the Joint Editor Tool (Alt+Shift+J).

    What are you trying to do?

    It's a design decision. if the object origin was in the centre then it would rotate about the centre, which might be useful, but it would also scale from the centre, which would mean repositioning it if it was placed on a surface - the developers had to pick one and hope it would be the most convenient option for most users.

    The red mark is the end point - if you want to change the orientation of the axes (for example, to straighten up a prop that's modelled off the axes to line up with a hand) you might want to use it, then use the Align option to snap the main axis to run from the origin to the end point but otherwise it doesn't really matter for props.

    Here's a work around for putting the universal manipulator (local coordinates) in the middle of an object. First measure your object. Second make a New Primitive plane (Create>New Primitive>plane) the same height and width as your object. The plane is sitting on the floor of the X, Y, Z coordinates. Third select the plane then go to Parameters and rotate around X axis 90 degrees. This will put the origin in the middle of the plane. Fourth, move the plane up by half the height of the plane which is the same as half the height of the object (in the Y translate box type the value of half the height in the upper right corner). Fifth, copy the position of the pane to the object, click the Scene tab and in the column that list the objects in the scene click control-C while hovering over the plane then move the cursor up to the object name, hover over object name and click control-V. That should force the universal manipulator (local coordinates) to the center of your object. You can also use the bone editor to move the universal manipulator but that's more work than doing it this way.
