AutoCAD Free Download 2022
The name "AutoCAD Crack" was chosen by the creator to refer to an "Automatic CAD"; the first version of AutoCAD Cracked 2022 Latest Version was designed to work by itself, and users could work at a terminal or by connecting a computer to it.
AutoCAD Crack Mac is a general-purpose 2D drafting and computer-aided design (CAD) application. Unlike other CAD applications, AutoCAD features a unique approach to creation and viewing of 2D drawing objects that includes features such as the ability to undo or redo drawing actions, and geometric feature support to create surface-form objects such as walls, floors, and ceilings. The software is also cross-platform. AutoCAD, and its prior incarnations, have been used to make AutoCAD drawings on both home and commercial PCs and Macs, as well as on Unix-based systems.
Since its initial release in 1982, AutoCAD has undergone many upgrades and refinements, and has continued to be the standard for drafting in the industry. AutoCAD's complexity and sophistication has allowed AutoCAD to be used in a wide variety of industries, as well as in architectural and engineering fields, to enable companies to build such diverse products as automobiles and buildings.
Like all software, AutoCAD requires periodic upgrades, and thus users of older versions of AutoCAD may need to upgrade to a more recent version of AutoCAD to continue to have access to the latest features and functions.
In AutoCAD LT, AutoCAD's low-cost, entry-level version, features are simplified and some design functions are not available.
AutoCAD LT 3.0 is designed to be a "next-generation AutoCAD", with many enhancements, such as supporting imported DWG files from other applications.
AutoCAD LT 3.0 was released in November 2013. This version was specifically targeted for use in a personal or classroom setting. It is a free download from the Autodesk web site.
AutoCAD Architecture
AutoCAD is designed to allow users to draw objects that are not predefined in the software. For example, in the drawing depicted above, the user has created a rectangle that is not predefined. The first step in drawing objects in AutoCAD is to enter an object name, or component name, to represent the object.
For example, in the drawing depicted above, a rectangle was
AutoCAD Crack +
InteliGlance is a C++ library that can be used by applications to recognize objects in AutoCAD Full Crack drawings.
In 2008, AutoCAD Central became a free service.  It is now hosted in a web interface.  Previously, it was provided through a software distribution product, Autodesk Central.
Drawing objects
In AutoCAD, drawing objects are geometric entities that can be created and manipulated using the drawing tools. They can be saved to file (e.g., DXF, DWG, JPG, TIF, etc.) and shared with other users. These objects can be grouped into layers. Each layer can be annotated with text, symbols, images, blocks, dimension boxes, and any other content including objects, image files, text and tables. The drawing layers can be used to group layers into drawings. In AutoCAD 2004 and earlier, the drawing layer was an option in the left-click menu and some drawing tools. In later releases, such as AutoCAD 2004, AutoCAD LT 2009, AutoCAD 2010, AutoCAD 2012, AutoCAD 2013, and AutoCAD LT 2013, the drawing layer was available as a command in the command line.
In AutoCAD 2011, a new method of organizing layers was introduced. Rather than having separate layers for each drawing object, layers were now shared across all drawings. This method of organization is generally easier to use. It is also easier to generate a general layer definition, which will be common across drawings, by using the Layer Manager.
Layers are not always mutually exclusive. For example, a complex drawing may have a layout layer, which includes a number of building layers, and a number of drafting layers. A typical drafting layer may contain a number of component layers, each of which may contain a number of drafting elements (e.g., boundary layers, symmetry, intersections, etc.).
A layer can be annotated with attributes. These include text (e.g., title, caption, key, etc.), images, block diagrams, and so on.
Tools for creating objects
In AutoCAD, drawing tools are used to create objects and lines. These include:
 Mechanical drawing tools – are useful for 2D/3D straight line and arc drawing
 Drafting tools – are used for creating 2D lines and arcs, such as 
 Bounding box
 Dimensions
 Drafting constraints
 Freehand drawing tools
 Geometric figures
