Since its inception, AutoCAD has been available on several different platforms including the Apple Macintosh, Microsoft Windows, OS/2 and Unix. Initially available in DOS and OS/2 versions, the Windows version of AutoCAD was released in 1991. Many of the features previously available only on the DOS and OS/2 versions of AutoCAD have been integrated into the Windows versions. Since 1998, Microsoft Windows is the only supported platform for AutoCAD.
Since the Windows release, there have been a number of new releases of AutoCAD, as well as numerous updates and enhancements. New features and functionality introduced in previous versions have been steadily incorporated in newer releases of AutoCAD.
Since 1994, the AutoCAD development team at Autodesk has focused exclusively on AutoCAD, making frequent updates and enhancements to the software. The release of AutoCAD R14 in 2011 marked the first time that there were major changes to AutoCAD as compared to the previous year’s release, AutoCAD 2009.

Major Releases of AutoCAD in 2012
Autodesk released a new version of AutoCAD called AutoCAD 2012 in May 2012. Key new features in the 2012 release include:
Improved support for cloud-based services such as cloud storage and access to other cloud apps from within AutoCAD.
This release also introduces support for the new Mac Pro and Mac mini hardware. AutoCAD now allows users to draw on Apple’s new high-resolution Retina display on the new MacBook Pro and Mac Pro. AutoCAD 2012 also supports high-resolution projects on these new Apple machines.
Multicore technology now provides the ability to run multiple threads of AutoCAD simultaneously on multicore Mac and PC machines. This technology makes AutoCAD more responsive to the user and allows for parallel processing to speed up execution time for some tasks.
The menu system has been completely redesigned with a number of new tools and features.
Although the 2012 version of AutoCAD is primarily focused on Mac and Windows users, there are also some changes that have been made to AutoCAD for Mobile.
With the release of AutoCAD 2012, AutoCAD software updates have been categorized into two categories, Design and Drawing Updates and Extensions Updates. The first category includes
AutoCAD uses a proprietary file format known as DXF, for two-dimensional drawing exchange format. The format is supported by several CAD applications besides AutoCAD. DGN and dxf2ps are older DOS applications, which support both DXF and DGN as file formats. These were replaced with DraftSight and dxf2CAD in Windows. There is also a free program called DXF2CAD which is a dxf2CAD port. DGN files can also be converted into DXF format using dgn2dxf. AutoCAD supports the following DXF-related features:
Auto-generation of components based on profile definitions
Automatic layout of parts
Support for many standard and nonstandard profile types and units
The formats are currently supported by the following AutoCAD programs:
The exchange of three-dimensional and shape data is done via the 3D Exchange format.
AutoCAD also supports an XML-based file format, ACAT. It is used mainly to exchange layer and annotation information between applications (e.g., in an architectural design suite). AutoCAD also supports an XML based format, DWGX, for exchanging data with SketchUp.
The first AutoCAD program was written in 1991 and it was called Autodesk Architectural Desktop. The name of the program was later changed to AutoCAD. The program was the first 3D CAD program to be available in the consumer market. The next CAD program was Autodesk Navisworks, which was released in 1994. In 1999, the software was renamed as AutoCAD. AutoCAD is now used for 2D and 3D drawings. The name of the software was further changed to Autodesk AutoCAD in 2002.
Each AutoCAD release has included a higher feature set and more robust performance than the previous release, for example, 2D and 3D design tools, surface modeling, 3D modeling tools, 3D viewer, and rendering, among others. Each release has also come with a new release of AutoCAD Architecture.
Recent developments in the area of design software include the introduction of 3D modeling into software, including architectural 3D modeling applications such as Zaha Hadid’s design software A-Frame (scheduled to be released in Q4 2010), and
Go to start.bin and double-click “rp2key.bat” to run the keygen.
Here are the main settings you have to make when using the keygen:
File Name and File Path: Enter the path where you installed the software and the file name of the.pbf file you downloaded.
Section(s) to be created or modified: By default, it should create the default layer named “Default”. It should be the only section created. It contains the data you imported into the database.
Layer Name: Enter the name of the layer you want to keygen.
Layer Type: By default, it is a line layer. You can choose the other layer types as you want.
Extension: Enter the extension (dwg,.dxf,.dwgx,.dxfx) of the layer file.
Extension Type: By default, it is DWG and DGN. You can choose the other extension as you want.
Existing Key File(s): Enter the path to the.dwg files which you want to keygen.
Key File Name: Enter the file name of the.dwg file.
Key File Path: Enter the path to the file you want to keygen.
Sketch Batch: Enter the batch number if you imported the.dwg files using Sketch Batch.
Auto key options: You can decide whether to key key line number, automatic key, full key, or none key (it will not key anything)
Keyline start: Enter the start position of the keyline.
Keyline End: Enter the end position of the keyline.
Point start: Enter the starting position of the point.
Point end: Enter the end position of the point.
Notes: There is no need to set the size of the key, the key will expand automatically when you insert the key into the DB.

Add new views directly from the Import Dialog, to create “one-click” views of your project. (video: 1:07 min.)
Erase all connected views and objects with one click, or erase only non-linked parts.
Automatic markup, so you can quickly view and edit your design with the familiar annotations, arrows, and numbers you are used to. (video: 3:14 min.)
Markup Assist is also available as a separate application, and is available for download for free.
Importing objects from GIS data:
Mapbox support for importing custom map data, even when your drawing is on another server. (video: 1:13 min.)
Automatic coordinate format detection for your drawing, to get the most accurate location.
Improved new drawing options that make it easier to switch between two views of your drawing.
Support for Shape Analysis Objects:
Shape Analysis Objects are a powerful new object type available in AutoCAD that provides access to a rich set of analysis tools, like the ability to analyze the points that make up a closed polygon or surface. (video: 2:55 min.)
Right-click on the Analysis Objects button to switch between three analysis tools: Create/Merge, Subdivide, and Determine Shape.
Right-click on an Analysis Object to perform a sub-analysis, creating a series of new Analysis Objects.
Drawing within objects:
Drawing tools (pencil, eraser, airbrush, and laser pointer) can be used inside an Analysis Object to make a pencil sketch of the shape.
You can access a 3D model that represents the geometry of an Analysis Object, so you can get a visual representation of the shape.
