2.5 Object origins
Before working with 3D modeling in Blender, it is important to
understand and learn how to manipulate some key properties of objects
in the 3D Viewport. One of those aspects is the object origin point, which
might help you place and edit objects with improved precision.
Where are object origins? You will find that most 3D objects in Blender
display a small dot with an orange color (Figure 2.16).

Every time you set the coordinates of an object using either the Sidebar
or the Properties Editor, you are using the origin point location as the
reference. If you set the coordinates to zero for all axis, it will be the
origin point that will stay at those coordinates.
