AutoCAD 2023 24.2 Activation Code Free PC/Windows [Latest] 2022


AutoCAD is a commercial CAD and drafting application. It is widely used by architects, engineers, construction professionals, illustrators, drafters, mechanical and electrical designers, artists, manufacturers, and anyone else involved in creating and editing a variety of 2D and 3D drawings, architectural and engineering models, and computer-aided design (CAD) models.

Its core audience is both “power users” who use it professionally on a daily basis and “do-it-all” home users, who can get a high level of functionality from a free and open-source alternative. AutoCAD is one of the world’s most popular and widely used CAD and drafting applications. It has been used to design numerous iconic structures around the world, including NASA’s space shuttle, the Sydney Opera House, the General Motors Technical Center, the Sydney Harbour Bridge, the Eiffel Tower, the Vatican City and the Burj Khalifa.

AutoCAD is a widely accepted substitute for other high-end CAD and drafting software like AutoCAD LT, Creo, Inventor and ArchiCAD.

AutoCAD relies on a proprietary 3D model database, usually stored on a local hard drive, that is accessible through a number of different methods. A model database allows a user to work on several documents at once, saving changes and creating, editing and moving objects.

Access to a model database can be limited. For example, a model may be loaded only when the computer is connected to a network.

Other storage areas include a local hard disk or pen drive and a USB flash drive, both for storing users’ personal data such as drawings and projects. The USB flash drive is also used for quickly transferring information to and from a desktop, mobile or web app.

Many people use a combination of desktop, mobile and web apps, or access AutoCAD through a server. With AutoCAD Server, users can work collaboratively and have their files accessible from anywhere via the Internet. AutoCAD Server is commonly used by schools, organizations and government agencies, to allow remote users to access the same model data as a desktop AutoCAD user.


AutoCAD LT is the latest version of the free and open-source AutoCAD for Linux. AutoCAD LT is a subset of the AutoCAD program that works only with 2D drawings. It is not affiliated with Autodesk

Entity framework

AutoCAD supports an Entity Framework (EF) for extensibility. Autodesk refers to this capability as “Infrastructure Entities”.

Using Infrastructure Entities (IE), one can add custom code into AutoCAD to alter the appearance or functionality of the application. Autodesk also released a free SDK (software development kit) for Microsoft Windows developers to use the Infrastructure Entities.

The Infrastructure Entity concept was first unveiled by AutoCAD 2000, and is now available in AutoCAD 2009 and in AutoCAD LT 2009. AutoCAD 2003 was the first AutoCAD product to offer Infrastructure Entities functionality. However, the object-oriented programming APIs (Application Programming Interfaces) available in AutoCAD 2003 only permitted customization of top-level items. Users were not able to customize the appearance and functionality of objects other than the top-level components.

AutoCAD 2013 introduced object-oriented programming APIs, so that the user is able to customize other objects as well.

In 2013, Autodesk introduced a change to the programming interface for AutoCAD. From this year on, all items will be presented in the way they are intended to be accessed and used. Previously, the user was able to perform more operations on a particular component than it was actually possible, which resulted in user frustration.

For AutoCAD 2014, a new ObjectARX API was introduced, based on earlier ObjectARX code that Autodesk had previously released for Autocad 2003.

The new programming model will make it easier for Autodesk developers to create new components and tools for the design program, which was a goal of the new model. AutoCAD 2014 is the first AutoCAD product to natively support dynamic symbols, making it much easier to quickly create and use custom symbols.

AutoCAD LT 2014 introduced new in-place editing, which allows the user to edit in place any shape and annotate them. Annotating is now easily done through editing of shapes directly, with support for change set, highlights and pattern.

AutoCAD and AutoCAD LT 2018 introduced a new “Arrange” and “Annotate” commands, which allows the user to “arrange” parts of objects on each other in a specific order. It is compatible with both AutoCAD and AutoCAD LT 2018.


AutoCAD 2004 added several specific features for creating and

Why does my write lock not release until I break out of the loop?

I’ve got a list which is being accessed by multiple threads. However, when a thread wants to access the list it gets a lock.
This code:
List myClassList = new List();

throws an System.InvalidOperationException “Invalid attempt to call WriteLock when reader is currently holding the lock.”
The reason is that some other thread, which is accessing the same list (i.e. the lock), is still holding the lock. This is fine.
However, if I remove the lock, the problem goes away. Why?


If you need to share the list, the behavior you are seeing is the expected behavior.
The lock(myClassList) method is not blocking other threads (that would be the case if you instead used a read lock). If you step through the method, you will see that the lock is indeed released immediately after the myClassList.Add/Remove calls.
It seems like you want to share the list and at the same time protect it from concurrent access. The simplest way to do this is to have a private read-only copy of the list with its own lock:
List myClassList = new List();

private readonly List protectedMyClassList = new List();

//Use protectedMyClassList

This way, all calls to protectedMyClassList are synchronized against each other.

“The next time someone tells you that the only way to get your number is to give it to them or to make them guess a number until you say it, tell them they’re full of shit. This is the real way to get your number, and if you don’t learn it now, you’re never going to get a girl. First, you need to get her to a crowded place, like the bus, subway, movie theater, or mall. When you get to a crowded area, you need to stand on line for a while. Once you’re in line, you need to know that you

What’s New in the?

Saving Timelines:

Make confident, informed decisions about what you draw, when you draw it, and how often you draw it. More comprehensive workflows and a smarter approach to content enable you to see, communicate, and document everything as you draw it.


Gain the ability to follow, repeat, and scale your knowledge as you discover different ways of solving a problem. With efficient collaboration, you and your team can access and incorporate the expertise of others.

Smart Objects:

Manage your drawing from one system instead of having to open your entire library across multiple platforms. Learn how to automate using the latest features of AutoCAD, such as object recognition.

Revision Control:

Avoid losing time by keeping your original drawings. The Revision History tool and Object History make it easy to track the changes to any drawing since you last saved the file.

Automate with ease:

Get your drawing to happen when you want it, regardless of your model or material. AutoExec, Air, and Object Accessible technology helps you to complete your tasks faster, and they offer more flexibility than programming.

Solve problems with workflow:

Get insights into your drawings with workflow tools, such as Dynamic Blocks, Conditionals, Text, and Dimension Adjustments, and then take action. These improvements to the user experience speed up the design process and make it easier to solve problems.


The new Navigator is the interface for navigating throughout your drawings. It provides easy access to design elements, tools, and other features. It can be customized, with options such as different default views and the ability to include or exclude parts of the Navigator.
