Have to set to object. It is not for adjusting orientations, it is for selecting orientations. After creating object there is no way that I can tell to determine what the original size was. Editing via info box almost impossible. The Object Info box shows both location, and size.
Location is the position in the world.
Size is the dimensions of the object itself. Editing with the Object Info box is very easy and quite powerful. Using arrow keys is the same. An alternate via dialog shoulf be provided. The Eye and Look tools can be set to any specific heights or points in space instantly using the Location Bar.
