The user enters data into the design window through the use of a keyboard and mouse (or a touchscreen and stylus). The data is saved as a file, which can then be opened and viewed by others. The file can be printed or sent to a page-layout program to prepare the file for commercial printing. AutoCAD Cracked Version also supports several other input methods including a pen tablet or light pen, digitizer pad, and tablet (see below). AutoCAD data files can be converted to other file formats, including Microsoft Word and Excel.
The development of AutoCAD's underlying architecture and processing engine was a team effort. Most of the internal code was developed by Eric B. Schultz, a programmer and designer hired in 1981 by Autodesk's marketing manager. Eric has since become Autodesk's director of technical marketing, and helped to write many of AutoCAD's major features.
Autodesk has developed AutoCAD along with an AutoCAD LT ("Light Table") version of AutoCAD. (AutoCAD LT is a free version of AutoCAD, which has far fewer features and is designed primarily for the home market.) AutoCAD LT was released in 1991. AutoCAD LT is not supported as a "true" Autodesk product, but is instead offered as an add-on product available for purchase from third-party developers, such as CADSoft and Xpert-Software. AutoCAD LT is also available as a mobile app.
AutoCAD LT lacks many features of the full AutoCAD product, such as support for parametric drafting (creation of drawings that can be built using parametric rules) and refit and associated commands. Some of the most important AutoCAD LT functions are available in AutoCAD's companion product AutoCAD R14 (in its Windows and R14 versions). AutoCAD LT does not support some of the most recent AutoCAD features such as 3D objects and layouts.
On October 14, 2010, Autodesk released AutoCAD for iPad. A second-generation iPad was released in March 2011, and a third-generation iPad was released in September 2012. On October 6, 2012, Autodesk announced that the iPhone version of AutoCAD is also now available as a free download in the App Store.
Since the introduction of AutoCAD, Autodesk has released numerous other software products, including Autodesk Inventor, Autodesk

3D modeling 
Cracked AutoCAD With Keygen includes a 3D modeler or "modeling environment" known as DWGspace or DGNspace. DWGspace allows users to view the same 3D geometry from any number of angles using perspective (polygonal models can be converted to wireframe, cross-section, or solids for rendering). DWGspace was originally the default workspace in AutoCAD LT and has since been integrated into AutoCAD.
 DWGspace has a simpler modeler than AutoCAD's, but still supports all of AutoCAD's capability. DWGspace was also used in Autodesk's 3D software subdivision of Autocad LT in 2007. 
The 3D workspace is divided into various types:
 Primitives: Specify objects as quadrilaterals, trinagons, and polygons.
 Mass: Create solid mass model.
 Surface: Convert 3D model to 2D.
 Surface Area: Calculate surface area of solid objects.
 Planes: Construct planes, solids, and surfaces.
 Texts: Add text to the workspace.
 Wireframe: Converts the 3D model to a wireframe or 2D plan view.
 Options: Set color, linetype, and lineweight for surfaces, lines, and text.
 Defaults: Set color, linetype, and lineweight to general options.
 On-screen adjustments: Display a worksheet with adjustment scales.
 Toolbars: Contains AutoCAD tools such as object snap, dimension, routing, command, and utilities.
 Modelling 
As the name suggests, modeling workspaces allow you to create models of objects within the workspace.
Creating objects
Models can be created from scratch, or from an existing file.
 Models are in ObjectARX format (.arx files).
The Model workspace has various options to create models, such as Placing, 3D, Cut, Extrude, Project, Fit, Mirror, Flatten, Move, Remove, Measure, Drafting, Geometry, and others.
AutoCAD LT supports DWG, DGN, and STL file format. Models in DWG and DGN formats can be imported into AutoCAD LT, which creates a separate drawing with a unique name (drawing.dwg or drawing.dgn) and is dependent on the original file. STL files must be converted to an appropriate format (e
