Autocad LT With the 2006 version of AutoCAD LT, Autodesk offers a more flexible and intuitive application designed to make professionals more productive than ever. Key features like more flexible hatching, improved dimensioning, and user-friendly text editing make AutoCAD LT 2006 a worthy upgrade from previous versions. Autodesk has also improved the user interface, enhanced the editing toolkit, and more--again, with the goal of increasing productivity for 2D drafting and detailing. Dimension with greater ease: New arc length and large radius dimensioning. Reduce waiting time: Plot jobs and spend more time drafting with background plotting, which allows you to continue working in the drawing editor while AutoCAD LT plots in the background. Mark up: Easily coordinate projects throughout design review with the markup and redlining functionality of AutoCAD and Autodesk DWF Composer. View DWF files: The free downloadable Autodesk DWF Viewer enables you to view DWF files that preserve design intent without requiring the original design application. AutoCAD LT is aimed at design professionals in all industries who require full DWG file format compatibility but do not require 3D capabilities or advanced customization of their software.
