In early 1987, the first version of AutoCAD was released for the Apple Macintosh and the Microsoft Windows operating systems. Since then, the software has been developed to operate under Microsoft Windows and macOS. AutoCAD 2012 is the newest version of the software.

AutoCAD and its related products are used in a wide variety of industries. These include architectural design, product design, landscaping design, flooring design, equipment design, and engineering design. AutoCAD software is sold for professional and commercial use.


AutoCAD is software which contains some of the features that allow users to design and draft three-dimensional shapes and elements. The idea behind AutoCAD is to facilitate drafting, design and editing of plans, sections, and elevations to create topographic workflows.


AutoCAD contains a range of features, including:



The most widely used of AutoCAD’s tools is the Drafting toolbox, which enables users to create, edit, or modify drawings of architectural design, engineering, facility management, or landscaping. The Drafting toolbox includes tools which enable users to create and edit three-dimensional (3D) views, including elevation, surface, section, and other similar views. Additionally, the Drafting toolbox enables users to create, edit, or modify 2D vector graphics, including paths and text, as well as raster graphics.

Alteration tools:

The Alteration toolbox allows users to design and modify three-dimensional objects. This includes creating, editing, and modifying non-topographic views of designs and architectural design.

Layout tools:

The Layout toolbox contains tools which enable users to design and edit layouts. These layouts can be used to create and modify floor plans, room layouts, site plans, and other three-dimensional views.

Modeling tools:

The Modeling toolbox contains tools which enable users to create and modify three-dimensional models of architectural designs, manufacturing or fabrication, mechanical systems, equipment, and other designs. It also enables users to create and modify three-dimensional object details.

Diagram tools:

The Diagram toolbox contains tools which enable users to create, modify, and edit two-dimensional diagram graphics.

Project tools:

The Project toolbox contains tools which enable users to create and modify two-dimensional project designs, including floor plans

The drawing data can be stored in a native format or exchange format (Exchange)
The Exchange format allows saving the drawings data as a CADX2 file, or as a native DXF file.

As of 2014 the standard CAD exchange format is called CADX2 (ISO/IEC 26262). The newest release (Autocad 2016) supports both formats.

AutoCAD is a D-I-S-S (Drawing, Interact, Scale, Show) drawing application program. D-I-S-S stands for “Directly from the Sketch”. It is one of the most important features of AutoCAD: This ensures that the viewer has access to the latest view.
Autocad uses a tree-based workspace and interface for storing, reviewing, moving, and assembling drawing parts, documents, and drawings.
AutoCAD has a number of tools, including pencil, line, block, rectangle, circle, text, fill, trim, and view tools.
It can be used to design three-dimensional (3D) objects and two-dimensional (2D) objects, including drawing and engineering.

Drawing elements
AutoCAD’s drawing elements include lines, curves, arcs, circles, text, images, and blocks. There are numerous options and switches to modify these elements, including the precision of the line, points, curves, and arcs.
The points are often not displayed when drawing lines, curves or arcs. This is to prevent the points from masking out too much of the objects. The points will display if any objects are drawn over them.
There is a zoom function in AutoCAD, allowing for high-level magnification on drawings.

AutoCAD is a multi-threaded, object-oriented, programming language that supports all three of the established programming languages: procedural, object-oriented, and functional. The procedural language is a text-based approach, object-oriented, and the functional language uses commands and messages.

AutoCAD uses 64-bit floating point to represent coordinates and other geometrical data. For compatibility with older versions of AutoCAD, only 32-bit versions of AutoCAD are available.

An object-oriented programming language is one which can be used for both object and non-object oriented programming, or both object and procedural programming. AutoCAD can support both object-oriented and non-object-oriented

Elevated levels of GATA-4 in human cervical cancer cell lines and cervical cancer tissues.
GATA-4 is a zinc finger transcription factor, which plays a crucial role in proliferation, differentiation and apoptosis. This study investigated the expression of GATA-4 and its relevance to human cervical cancer. In this study, we found a significant overexpression of GATA-4 in human cervical cancer cell lines (HeLa, SiHa, and CaSki) as compared with in normal human cervical epithelial cells (Ect1/E6E7). In addition, the overexpression of GATA-4 was found in cervical cancer tissues as compared with normal cervical epitheliums. The elevated expression of GATA-4 was demonstrated by Western blotting, immunohistochemistry and immunofluorescence staining. Furthermore, we showed that overexpression of GATA-4 promoted the proliferation of cervical cancer cells. These results suggest that GATA-4 may play an important role in the growth of cervical cancer.A second blood disease that causes bone marrow failure has been identified in seven dogs, according to a study conducted at Colorado State University’s Companion Animal Veterinary Medical Center.

The disease, termed hemophagocytic lymphohistiocytosis, or HLH, is a disorder that resembles a bacterial infection. In the dogs in the study, a condition known as infectious mononucleosis caused the symptoms, but as time went on, the dogs became more ill and their illnesses became worse.

This led to an increased number of blood cells in the bloodstream and problems with the bone marrow. The condition is believed to be immune-mediated, meaning it involves the immune system and is triggered by an infection.

The dogs in the study were treated for about six months, and the authors report that, in each case, the HLH symptoms improved as the dog’s immune system improved.

“This is the second in a series of studies to identify a disease called hemophagocytic lymphohistiocytosis, or HLH, in dogs,” said Dr. Christin C. Crawford, owner and director of the Companion Animal Veterinary Medical Center and an associate professor in the department of internal medicine at Colorado State University. “A single blood test is all that
