AutoCAD 2023 24.2

AutoCAD Product Key remains the market leader in CAD, and is the primary 3D computer-aided design (CAD) software used in the architectural and engineering fields. There are also software alternatives to AutoCAD Free Download, such as free and open source BRL-CAD, MacCAD, and LTSpice, as well as commercial CAD alternatives, such as Trimble Design Suite, SketchUp, Netfabb, Vectorworks, and CorelDRAW.


AutoCAD Crack’s origins go back to 1982, when James Gosling and John Warnock created a program called “DraftSight”, which was an on-screen vector drawing program for the Apple II, written in the BASIC programming language. The program used overlaid bitmap graphics called “clipping masks” to create shapes and handle bezier curves. One of the first bezier curves found in the Apple II world was used to create an airplane drawing and Gosling and Warnock named it after the Wright brothers. The first version of the original program was called “DraftSight”, and ran on an Apple II with a 15-inch (38 cm) display.

In 1983, Paul Rathjen (who worked with Warnock and Gosling at the University of Utah) joined Gosling and Warnock at Hewlett-Packard (HP), who was then developing a 16-inch (40 cm) desktop computer display for the Apple II called “HP-48”. The application was written in assembly language. Initially, Gosling and Rathjen worked on the graphics functions for the “DraftSight” code. However, Gosling was more interested in the graphics programming, and Rathjen took over the overall programming. Gosling and Rathjen then named their new program “AutoCAD”, short for Automatic Computer Aided Design.

In 1984, Gosling, Rathjen, and Warnock released a second version of “AutoCAD”, called “AutoCAD Version 1.0”, to the public. In 1985, Rathjen and Gosling left HP and the company was sold to NCH Software Inc, who started marketing “AutoCAD” in November 1985. The first version of “AutoCAD” (for the Apple II) was accompanied by a 16-page manual and source code. The first version of the software was developed with high-resolution bitmap graphics and 16 colors, allowing the Apple II to display up to 256 colors (16 x 16). The first version also

AutoCAD software works on Windows, macOS and Linux, and is available for both professional and home users. CAD software requires a substantial number of resources to operate, so using the appropriate computer hardware is key.

The basic requirements are:

512 MB RAM (RAM)
100 MB disk space (CAD and other operating systems will use this disk space for AutoCAD’s working files)
An operating system compatible with that of the CAD software. AutoCAD runs on Windows, macOS, and Linux.

AutoCAD software is now available for laptops and tablets, including Android (software) and iPhone/iPad/iPod Touch (OS). As of January 2013, all standard AutoCAD applications were available for free for iPad, iPod touch and iPhone devices with the iOS version of AutoCAD.

AutoCAD runs on Microsoft Windows, macOS, Linux and in virtualised environments such as VMware Fusion and VirtualBox.

AutoCAD is released under a business model called perpetual use in perpetuity that requires annual subscription fees and a fee for each project.

AutoCAD software can be licensed by subscription for one or more users, or licensed on a one-time basis (as an activation code) for a number of seats, at a fixed price, with no ongoing fees.

Autodesk licenses AutoCAD as “perpetual use in perpetuity” that is required for each unique user. “Perpetual use” means that the annual subscription for each user of AutoCAD is a one-time payment, and that no ongoing fees are required.


On April 19, 1990, Autodesk started development on AutoCAD, to produce a 3D architectural CAD system (previously there were just 2D CAD systems). Autodesk’s product was designed to be as easy to use as a CAD system could be. This was contrary to the philosophy of most other CAD programs at the time.

The primary goal of the product was to create a flexible system that would meet the needs of the architecture, construction and engineering industries, and not just the design community. To accomplish this goal, the product had to focus on specific tools that architects and builders needed for the working environment of these fields, while creating a feature set that was simple to use and approachable by anyone, regardless of skill level. To this end, Autodesk succeeded in creating a CAD system that was easy to

What’s New In?

You can also use Zoom&Measure to quickly import measurements and 3D models into your drawing. Now, with Zoom&Measure you can select objects in your drawing, and immediately see the measurements, or preview a 3D model for that object.

Zoom&Measure also includes Snapping, which displays a grid at your cursor position to help you correctly position objects.

In addition to the new Sync option for animating your drawings, you can now also Sync objects by using Object Snapping.

Markup Assist:

You can now create markers for various kinds of data and automatically receive comments and follow-up questions from annotators.

If you mark a box as “Markup Assist” in the Markup panel, users can reply to your comments directly from the box.

This new interface is controlled by a new AutoCAD option: Enable Markup Assist. With this option, the Markup Assist panel appears when you create a new Markup style.

To use the Markup panel, click the “Markup” button on the Markup panel ribbon to display the Markup panel. You can add markers to the drawing by clicking the objects in the Markup panel.

To use Markup Assist, first create a Markup style, and then in the Markup panel’s options, choose Enable Markup Assist.

Markup Assist now includes several new tools, including a rectangle, a polygon, an ellipse, a circle, a line, an arc, a text box, a line graphic, and several marker types. When you mark objects with a marker, you can specify a color, a placement area, and an anchor point to make sure your marker appears where you want it to.

You can also add a text label to your marker to include a title or a description.

You can also add a dashed, dotted, or dotted-dashed line to create a boundary for your marker.

You can use an arrow to indicate that your marker is sensitive to changes in the drawing.

You can also create a marker that will automatically create an audio comment when the marker is clicked.

A new option, Delay on Markers, enables you to set a default delay time between the click of a marker and its appearance.
