We can quickly transfer the local coordinate system from one object to another by joining and next separating them, or by performing the “Align to Transform Orientation” operation with the “Affect only Origins” option turned on.
Transferring the local coordinate system through the objects joining and separating
Select an object to which you want to transfer the local coordinate system from another object.
Locate the 3D cursor at the origin of the selected object – press shift + s and select “Cursor to Selected” in the popup menu.
With the Shift key held down, select the second object – from which you want to transfer the local coordinate system to the first one.
Press theĀ Ctrl + j key combination to join the selected objects.
Switch to the Edit mode (by pressing the TAB key) and select the first object.
Press the “p” key and select “Selection” to separate the first object.
Switch to the Object mode (TAB).
Select the object, click once with the right mouse button and select Set Origin – Origin to 3D Cursor to restore the original position of the object’s origin.
