Figure 2.19 - 3D Cursor aligned to the Cube

After you align the 3D Cursor, you can go back to Object Mode and use

the Object → Set Origin menu. There you have an option called Origin

to 3D Cursor. If you choose that option, you can change the location of

your origin point to be the same location as your 3D Cursor (Figure

2.20).
