The first version of AutoCAD came in a “bare-bones” version, and it did not contain many of the features available in later versions. The basic idea of the AutoCAD software was to provide a simple interface between the user and the computer, so that the user did not need to know how the computer actually works. This interface consists of a user-friendly command bar and other on-screen visual tools. The first two versions of AutoCAD did not have any commands at all, so to use the software, a user had to learn from someone else how to perform specific tasks.
In its original version, AutoCAD had no model, raster or vector capabilities. To create a simple sheet metal drawing, a user had to use the “Simple Drawing” command, which created a graphic pattern based on the first few commands on the command bar. The drawing is then manipulated by use of the mouse. In the original version, this model could be traced on a sheet of paper, after which it could be measured and cut out and welded together to make a simple sheet metal prototype. In contrast, most AutoCAD users today use vector-based objects to create drawings.
AutoCAD introduced the concept of a data repository and software architecture. In the original version, it stored the drawing objects in the form of a collection of files, separated by the user. As additional revisions were made, the drawing objects would be added to the repository in the same order that the revision was made. Many of the objects used in later versions of AutoCAD were developed in this original software architecture.
Since its introduction, AutoCAD has gone through many upgrades and revisions. Major updates occurred in 1983, 1987, 1992, and 1999. Later upgrades have been minor or incremental. The more recent releases of AutoCAD and other software have been moving toward a concept known as “design for the cloud”. This means that the software is becoming cloud-ready, so that it can be hosted on the web instead of requiring a full-time, dedicated hardware installation. This has allowed many more designers to use AutoCAD, and it has greatly increased the availability of AutoCAD from both a desktop and a web/mobile standpoint.
AutoCAD uses object-based design. An object is any item on a 2D or 3D drawing. Drawing objects are composed from other objects. The objects in a drawing are grouped into layers, where each layer contains objects of similar design elements
The current version of AutoCAD is 2016. AutoCAD LT, the current entry-level model, is available in a free version.
AutoCAD-based programming languages
AutoCAD supports a wide range of programming languages.
AutoLISP is an AutoCAD extension language developed by Chuck Syverson. He was a software developer at AutoDesk in the 1980s who is responsible for the introduction of AutoCAD in 1984. AutoLISP was the first programming language supported by AutoCAD. AutoLISP code is not compiled, but runs natively in AutoCAD as machine code. It is a pure interpreted language, with no compiler. Each object that appears in the drawing is implemented as a Lisp symbol, which has a unique Lisp reference. The language features include:
integrated case statement and assignment syntax
fully integrated goto and break statements
fully integrated arithmetic and comparison operators
fully integrated global and local variables
fully integrated arithmetic and floating point operations
fully integrated subroutine calls and returns
integrated and user-controllable loops
fully integrated and user-controllable macros
fully integrated object callbacks
fully integrated and user-controllable function calls
fully integrated and user-controllable try…except…finally
fully integrated and user-controllable switch statement
fully integrated and user-controllable standard input/output
fully integrated and user-controllable input/output
fully integrated and user-controllable error handling
fully integrated and user-controllable object methods
fully integrated and user-controllable object-to-object communication
fully integrated AutoLISP data types
AutoLISP came to its demise when AutoDesk announced their decision to not develop further AutoCAD add-on products based on AutoLISP. The reason for this is that AutoLISP is based on Lisp (an esoteric programming language) and as such, it would have been difficult for AutoDesk to maintain a team to support it. This meant that the add-on product in its final form could no longer run AutoLISP code and it would have to be rewritten in a suitable language to run on the company’s.NET framework.
Visual LISP was developed by NCR Corporation and introduced by the company’s Autodesk subsidiary in 1985. NCR developed Visual LISP as a successor
Right click on Autocad and select ‘keygen for Autocad’.
Autocad will now ask you for the key.
Enter the key.
Autocad will load.
How to install
Download Autocad for the dll’s from the link below and extract the files to the Autodesk install folder.
Note: If you are using an older version of Windows you will have to rename the files to.exe.
If you do not have the dll’s or.exe file, you can download them from this site, by selecting Autocad for Windows (x86 or x64).
Cannot find the keygen
Verify that you have the keygen activated: Right click on the Autocad application icon, select ‘Options’, and under ‘Help’ tab, look for a ‘Search Help’ button. If you do not find a button, you do not have the keygen activated.
Win 10 users, here is how to get to the options menu:
Go to this path:
Then navigate to ‘AutoCAD_for_Windows’ and open up ‘Help’.
Use Setup from Autocad for Windows and enter a serial number and key.
I had the same problem. The keygen works as advertised. However, upon opening Autocad it does not load. I had to reinstall from scratch and was able to load Autocad and all of its components.
