Up Axis Constant locks the vertical axis during rotation so you can more easily navigate 3D architectural models. Center of Rotation sets the point about which 3DOrbit rotates, which is useful for mechanical models. Textured materials, transparency, and lights are now supported by the 3Dorbit and Render commands, as well as by shade mode, allowing a more realistic environment for modeling. Hardcopy enhancements Plot styles now support true color, finally breaking AutoCAD's archaic 256-color barrier. True colors display in drawing lay-outs and full plot previews.
Plot merge control sets the order in which overlapping objects plot.
Integration of AutoCAD LT features You can drag and drop hatch patterns from other drawings directly into the current drawing. All properties of the existing hatch are copied to the new drawing. The new Purge dialog box provides a simple interface for purging all nested entities with a single command. The Array dialog box adds numerous controls and a preview mode to simplify AutoCAD's rather tricky Array command. A natural-language query engine provides easy access to AutoCAD's Help database, which now includes tips and techniques to further increase your productivity.
