AutoCAD is a widely used, multi-platform computer-aided design (CAD) and drafting software. AutoCAD is available as a mobile and web app on Android and iOS. The free version of the software runs on Mac and Windows systems.
AutoCAD has been the most widely used desktop CAD software for commercial enterprises since its introduction in 1982. Originally developed as a desktop app for a single user to use on a computer with a graphics card (graphics processor) it quickly grew in size and scope. At the time of its original release, it was one of the first commercial CAD applications to provide a comprehensive set of commands and functions.
For various reasons, many CAD programs eventually found their way to the desktop of a single user, although many users opted for PC-based CAD software such as MicroStation for their personal needs. It was not until the introduction of PC-based CAD software on Apple’s Macintosh platform, however, that the desktop CAD market became viable and more widely available. Apple introduced a similar CAD program in 1989, called CorelDRAW, which took advantage of the new PowerPC chip technology. While Mac users quickly embraced it, Windows users at the time seemed less keen.
What follows is a brief history of AutoCAD.
History of AutoCAD
1983 – Autodesk first introduces AutoCAD, and its initial release is on a Macintosh and a PC. By the end of the year, it is expanded to an 80386-based machine, offering 32,768 levels of precision in two dimensions (X and Y).
January 1984 – AutoCAD is introduced on an IBM mainframe, and by the end of the year on the first Pentium based minicomputer, the NewTek 20.
1985 – The first version of AutoCAD on the IBM PC, as its name was then (AutoCAD) offers dual precision, with a floating point for 2-D and an integer for 3-D.
December 1986 – A Macintosh version is released, allowing the Autodesk Computer to offer the first professional-quality CAD package for Macintosh.
1986 – AutoCAD is first released for Microsoft Windows.
1988 – A variant for the Apple Macintosh platform, first called AutoCAD Map, is introduced.
September 1988 – Autodesk releases a generic version of AutoCAD for the PC, Mac and Apple Macintosh platforms.
1990 – The name
AutoCAD Activation Key [Mac/Win] (Updated 2022)
Programming
Many programming languages are used to create AutoCAD extensions and add-ons. These include AutoCAD’s own standard programming languages, Visual LISP and Visual Basic, C++, AutoLISP, Adobe Systems’ Flash ActionScript, and programming languages compiled to x86 (the x86 and x64 versions of AutoCAD are almost identical except for the memory limits of each version) and/or the assembly language. The Assembler component of AutoCAD can also produce x86, x64 and ARM assembly code for the commands it generates.

I have a script that automatically updates my database.
At the moment it searches for a certain row with the same specific information and updates that particular row.
But i want it to update all records of that table that have that specific value.
So for example if i have 3 rows of that table, and i set one value to one record, and 2 to another one, but i set the 3rd value to another record, it would update the first 2 records aswell.
What is the best way of doing this?
This is the code that checks for that record:
$updateSQL = “UPDATE `accurinti` SET `Total` = (SELECT SUM(`Total`) FROM `accurinti`
