Picking the Origin point from the basic bound box

You can use a more basic approximation for alignment by using a global bounding box surrounding the local bounds of the object. This bounding box ignores the object’s geometry, which usually means that it will not exactly touch the projection Plane when aligned.

To use this bounding box, you can disable the button Use geometry in the Origin point panel, or by using the shortcut Ctrl + G.

The local bounding box will also be drawn in this mode, so that you can see the relationship between the two boxes.
