After reading a few post and some tutorials, it seems to me the a mesh object is (indicatied by the violet ball in the 3D view) and the actual Mesh object data(indicated but the black lines and smaller violet balls in the edit mode and violet lines in the object mode) can have different orientations.
I have learned that they can have different locations in the 3d view and that you use the center,center new and center cursor buttons to change that location.
But if i thougt that they both had the same orientation that was only changed when you rotated the wireframe mesh object. If it is true that then can have different orientation how do you show the axis and their orientation of the object( the purple ball)?? I know you can use draw axis to show the oreintation of the puple mesh.
