The emphasis in AutoCAD 2008 is on 2D, especially on annotation. This fits with Autodesk's parallel emphasis on making AutoCAD appear to be a 2D product. The user interface is not much different, other than the addition of new buttons and droplists. Some changes were made to make AutoCAD more compatible with ADT (now renamed AutoCAD Architectural 2008) and Inventor. ADT 2008 junks VIZ Render in favor of AutoCAD's mental ray rendering engine. In turn, AutoCAD lights now support wattage information and IED data. Materials have new properties, reflect light better, and also support the IED standard.

AutoCAD 2007 moved all of the layer-related Express Tools into the core command set. One of them, LayIso, has been enhanced. In the past, it turned off all layers, except the one belonging to the selected object (hence, isolating it). New in 2008 is the ability to fade the other layers, rather than just turn them off. The faded layers are locked: you can see them and osnap to them, but cannot edit them. Very nice touch!
