As of 2013, AutoCAD is the second-most-used CAD program in the world, with over 15 million licenses sold. This article covers AutoCAD 2016, the latest version of the program, which you can download for free. If you want to learn more about AutoCAD’s history and design, see the introduction to AutoCAD in this article.
Update 8-13-17: This article is updated to include new information about AutoCAD 2018 and its features.
While some of the features of AutoCAD were already present in other Autodesk programs, such as Inventor and Project, the total package of AutoCAD is far more robust than these tools, and also more feature rich than any other generic CAD package.
I’ll start by explaining some of the basics of AutoCAD, then walk you through each of the main screen elements. I’ll give you tips on how to find the tools you need and how to create useful features. Finally, I’ll describe a few of the more advanced features you can use.
AutoCAD is the world’s most widely used drawing application. The program was first released in 1982, and is still actively developed today.
In AutoCAD, you create drawings for 3D models, 2D drawings and plans, and engineering projects, including buildings, bridges, aircraft, and ships. You also can edit photographs and create 3D models.
AutoCAD is also used to create and edit 2D drawings, like floor plans, blueprints, and architectural drawings. It can handle thousands of details and is ideal for drawing railway tracks and road and building plans.
AutoCAD’s 3D features include the ability to create the 3D models of buildings and other objects, and you can then add 2D drafting features to them.
While AutoCAD is powerful enough for many needs, it’s also easy to use. It has a keyboard shortcut, mouse-based interface, a color-coded system of grids and dimensions, snap to points and intersection, and very powerful menus and toolbars.
AutoCAD has four types of views that you can switch between by using the View button on the toolbar. You can use 2D drafting views (usually placed near the top left of the screen) and 3D drafting views (usually near the bottom left of the screen) or switch between them. In the
AutoCAD has also included a visual LISP interpreter since AutoCAD version 1.0 and 2.0 (1991). Its name was changed to Visual LISP (VSL) with the release of AutoCAD 4.0 (1993). VSL was originally used to add custom drawing features to AutoCAD. VSL can also be used to run dynamic macros (macros that are programmed in the drawing editor, rather than AutoCAD Scripting) and AutoCAD Scripting.
A VSL macro can be created in any of AutoCAD’s drawing editors, then exported as VSL. As a result, the macro can then be imported into AutoCAD. Alternatively, one can create the macro directly in AutoCAD. AutoCAD’s drawing editors allow you to incorporate visual code into AutoCAD drawings. The macro code can be seen by the user during the drawing process. VSL’s macro editing capability does not work for dynamic macros, that is, macros that are triggered by drawing events and not by data entry.
Visual LISP (VSL) was originally written by Brad J. Crider, then maintained by Kevin Lindley and later Wayne Gatland. VSL is a product line of AutoCAD and was the predecessor to AutoCAD 4.0, and 3D Objects. VSL was also a predecessor to the AutoCAD 5 extended capabilities for architectural drafting. AutoCAD 2.5 (1995) included VSL support for macros that act on drawings in the active drawing. AutoCAD 3.0 (1997) introduced VSL support for a user interface (UI). Although VSL’s capability included macros, it was not a programming language per se. AutoCAD 3.5 (2001) included a programming language called Visual LISP for Windows and Visual LISP for Windows 2000 (the last release of VSL before it was replaced by ObjectARX). The Visual LISP syntax has been retained by ObjectARX (see ObjectARX and the Visual LISP tag).
AutoCAD 6.0 (2005) introduced ObjectARX (Object-Oriented ARchitectural Software eXtensions), an ObjectARX-based API, and was discontinued with the release of AutoCAD 2012 (2011).
Open the Autocad and go to File->Options->Keygen Utility.
Enter your serial number in this window, then click the button.
The keygen will generate a new file with “a-x.reg” extension.
Close the Autocad, paste this file into the Registry, restart your computer.
The New York City Fire Department has warned residents to brace themselves for “some very cold weather” in the coming days, as temperatures dip into the 30s and 40s.
The Metropolitan Transportation Authority issued a travel alert for Friday evening, urging people to “be ready to ride” if they must ride home on the subway, and a spokesman said the safety of subway riders is the transit agency’s top priority.
“People who live and work in the city should be prepared for cold temperatures and extreme wind chills,” the authority’s spokesman, Aaron Donovan, said in a statement.
The National Weather Service is calling for frigid conditions across the region, and forecasters are predicting a “dusting of snow” to mix with freezing rain on Saturday.Q:
Does the standard’s explicit mention of std::function consider it to be a template in C++17?
I am reading P0778R0, in which the proposal clarifies that std::function is a non-type template parameter. The proposal specifies that the way to represent a non-type template parameter is like a dependent name, and says that its type is “dependent on the template parameter type”.
In the case of std::function, the type is std::function, and the parameter type is T.
Given that std::function is an implicitly-declared type (see [implicit.unqualified]/4), does this mean that std::function is considered to be a dependent name in the sense of [dcl.dcl.special]/22.214.171.124.5?
If so, then I am confused why it is not explicitly mentioned in [dcl.dcl.special]/126.96.36.199.5.6 that a template is a dependent name.
No, std::function is not a template.
[dcl.dcl.special]/188.8.131.52.5 (emphasis mine) states:
