Equipped with the right applications, a computer can be of great help in virtually any domain of activity. When it comes to designing and precision, no other tool is as accurate as a computer. Moreover, specialized applications such as AutoCAD give you the possibility to design nearly anything ranging from art, to complex mechanical parts or even buildings.
Suitable for business environments and experienced users
After a decent amount of time spent installing the application on your system, you are ready to fire it up. Thanks to the office suite like interface, all of its features are cleverly organized in categories. At a first look, it looks easy enough to use, but the abundance of features it comes equipped with leaves room for second thoughts.
Create 2D and 3D objects
You can make use of basic geometrical shapes to define your objects, as well as draw custom ones. Needless to say that you can take advantage of a multitude of tools that aim to enhance precision. A grid can be enabled so that you can easily snap elements, as well as adding anchor points to fully customize shapes.
With a little imagination and patience on your behalf, nearly anything can be achieved. Available tools allow you to create 3D objects from scratch and have them fully enhanced with high-quality textures. A powerful navigation pane is put at your disposal so that you can carefully position the camera to get a clearer view of the area of interest.
Various export possibilities
Similar to a modern web browser, each project is displayed in its own tab. This comes in handy, especially for comparison views. Moreover, layouts and layers also play important roles, as it makes objects handling a little easier.
Sine the application is not the easiest to carry around, requiring a slightly sophisticated machine to properly run, there are several export options put at your disposal so that the projects itself can be moved around.
Aside from the application specific format, you can save as an image file of multiple types, PDF, FBX and a few more. Additionally, it can be sent via email, directly printed out on a sheet of paper, or even sent to a 3D printing service, if available.
To end with
All in all, AutoCAD remains one of the top applications used by professionals to achieve great precision with projects of nearly any type. It encourages usage with incredible offers for student licenses so you get acquainted with its abundance of features early on. A lot can be said about what it can and can't do, but the true surprise lies in discovering it step-by-step.
History of AutoCAD
AutoCAD is widely used in professional architectural and engineering fields. It has a large installed base of more than 11.7 million users worldwide, according to a 2016 Autodesk survey. The software was originally developed as part of the Autodesk Plantum software suite, which was released in 1980. It was known as Autocad and the internal unit number for the software package was UDCA000. The first version of AutoCAD was released in 1982.
For several years the software was the CAD package of choice for many architects, engineers, and draftsmen. It was the number one market-share player in the CAD market in 1989 and 1990, according to a 1990 Gartner Group report. AutoCAD was named on Computer Associates’ list of the world’s most important software products in 1984.
AutoCAD was used by engineers in the design of the Golden Gate Bridge in the early 1980s and a section of the Channel Tunnel in the mid-1990s. However, by the early 2000s, the CAD software had largely lost its market share to more advanced competitors, such as Onshape, Revit, Trimble Dimensions, and others.
In 2009, AutoCAD was replaced by the newer AutoCAD LT. AutoCAD LT has a number of basic functions (rather than the full CAD/Drafting functionality found in AutoCAD) and is easier to learn and use. It was replaced in turn by AutoCAD Architecture in 2014. AutoCAD Architecture features a much simpler interface and allows architects to make basic design changes easily.
On March 4, 2017, Autodesk announced the release of AutoCAD LT 2018, the first update to AutoCAD LT since 2011.
AutoCAD is generally used for computer-aided drafting and design, construction drafting, rendering, and visualization (architectural design and landscape design). AutoCAD is used by architects, engineers, and drafters as a general purpose CAD program, or to create a variety of specialty tools and templates.
The following is a list of features in the current version of AutoCAD.
Layout: draw and update text boxes, dimensions, reference planes, and selected objects on layout views, such as floor plans, elevations, and sections;

The first commercial version of AutoCAD was AutoCAD 2.0, developed by Autodesk and distributed by Borland Software Corporation, who were acquired by Autodesk in the year 2000. The first version was developed by Ivan T. Sanderson and Doug Engelbart in the early 1980s, and was released for the Apple II in April 1984.
Autodesk began in 1984 with a drawing suite called „Drawing Utilities” or „DWU” that consisted of two programs: DWUH and DWU. DWUH was an autoconverter, while DWU was a viewgraph package which included the ability to create overlapping layers. DWU was also the first implementation of AutoCAD, although it only included basic functionalities. It was written by Doug Engelbart and Ivan T. Sanderson. The program was originally written for the Apple II and was available in 1981.
AutoCAD for Windows
AutoCAD was available for Microsoft Windows beginning with AutoCAD 2000. (AutoCAD 95 had been available for Windows through Autodesk’s AppLink, then discontinued in 1998, and had only a subset of features available.) Both AutoCAD 2000 and AutoCAD 2002 used a file extension of.dwg for the native drawing file format, and supported DWG as a file format for importing and exporting. The native file extension of AutoCAD 2013 was.dwf and no longer supports DWG. AutoCAD 2013 also introduces a new native native file extension.rvt for the native rendering format.
AutoCAD LT was developed to address the limitations of AutoCAD’s DWG format and price. It adds the ability to render drawings, and offers the ability to create, edit and view drawings with 2D layers, and modify the model and drawing file. It also provides a general purpose solution for the same kind of content for 2D drawings as AutoCAD.
AutoCAD LT is intended to be a low-cost solution for small businesses or individuals. In addition to rendering, it provides the ability to create and modify drawings and pages, export and import drawings to DWG and other formats, and offers a library of tools for document review and editing, including optical character recognition (OCR). A comprehensive set of libraries and a multitude of sample files are included with AutoCAD LT, and content libraries are sold separately.

Optimization of a scoring method for assessment of post-transplant lymphoproliferative disorders.
Post-transplant lymphoproliferative disorders (PTLD) remain a significant cause of morbidity and mortality after solid organ transplantation. Here we report on an attempt to develop a scoring system for the evaluation of PTLD. The study included 64 adult transplant recipients with PTLD, and 246 adult transplant recipients without PTLD. Induction therapy prior to PTLD diagnosis included rituximab in 27, cyclophosphamide in seven, and no induction therapy in 30. The mean time from transplant to PTLD diagnosis was 1.5 years. Receiver operating characteristic curve analyses showed a reasonable relationship between scores and PTLD status. Thus, a scoring system based on only three variables (number of years post-transplant, immunosuppression, and CD4+ T-lymphocyte count) had an area under the receiver operating characteristic curve of 0.72 (95% CI, 0.63-0.81). For an acceptable false-negative rate of 25%, a cutoff value of ≥1.85 points would be needed to confirm the absence of PTLD. This scoring system is a simple and fast tool to help in the differentiation between PTLD and other causes of lymphadenopathy after solid organ transplantation.New Guidance for Molecular Docking in Drug Discovery: The Missing Link?
Molecular docking is used in an ever-growing number of research applications in drug discovery. Its applications are, however, highly diverse and far from being well-understood or standardized. Docking is often used as a pre-screening tool to identify and prioritize molecules for experimental testing. Although this process has been performed with less success than expected, this article argues that it is nonetheless an important step in the early stages of the drug discovery process. Using a modern machine learning approach (neural networks) and a large, benchmark data set (13.7 million training molecules and 4.9 million test molecules), we
Markup import features the ability to add and delete objects and change the position and scale of existing objects. Remove unwanted objects with your keyboard, and change the size, position and/or rotation of objects with a mouse or touch screen.
You can import multiple files at once and combine them into a new file. AutoCAD can import text, line, and bar styles, symbols, and text alternatives, as well as traditional CAD-style geometry, such as lines, arcs, polylines, circles, and ellipses.
You can have multiple markup files open at once and insert the newest file into any of them. To learn more about the markup features, view the “Markup” section of this video.
