Cracked AutoCAD With Keygen is the world’s most widely used commercial CAD application and is the dominant application for 2D design and drafting in the architecture, engineering, construction, and landscape architecture industries. AutoCAD and Inventor (for 3D design and drafting) are Autodesk’s principal products for 2D and 3D design and drafting, respectively.


The earliest CAD software programs were developed on mainframe computers with dedicated graphics terminals (graphics terminals for drafting and graphics terminals for drafting and editing). Mainframe computer programs were typically software packages running on proprietary operating systems and graphics libraries, written in assembly language. As computer processors became faster, software and peripheral manufacturers combined to create microcomputers that were smaller, cheaper, and more portable than the mainframes. With the advent of desktop personal computers in the late 1970s, the need for dedicated graphics terminals went away. CAD packages that were formerly run on mainframes, minicomputers, and workstations could now run on desktop personal computers. As CAD packages became more portable and easier to use, the share of dedicated CAD workstations declined. Today, most CAD work is done on the desktop or on mobile devices.

Commonly used CAD software packages and their history:

Initial Development of AutoCAD

Autodesk did not initially develop AutoCAD as a CAD package. Its initial development started in 1978 when, as a small company, Autodesk’s founders, Andrew Evans and Kevin Lynch, wanted to create a user interface for engineering and drafting that was based on the graphics terminals used by architects, civil engineers, and other drafters. A graphics terminal was a time-sharing computer application that a drafter could use for drawing, but a command-based user interface would not be as intuitive or convenient as the command-based interface of the pioneering drafting program that had been introduced to the marketplace by IBM, IDLE™.

The founders of Autodesk identified the need for a software package that would run on mainframe computers, portable personal computers, or microcomputers with attached graphics controllers. Their goal was to create a graphics terminal with a command-based interface that would be easy for drafters to learn and operate. By 1978, the founders had developed the first version of AutoCAD.

Initially, AutoCAD was a command-based application that ran on a computer with an internal graphics controller (what Autodesk calls an “Internal

What is the purpose of SqlDependency in System.Data.SqlClient

I am writing a simple WPF application which needs to do real time SQL Server database connection.
However, I came across System.Data.SqlClient.SqlDependency class which looks a bit complicated.
My questions are:

What is the purpose of this class?
Is it worth to use?


This class provides automatic and timely notification for changes in underlying SQL database. This notification is implemented in C# using a SQL Server trigger.
From MSDN:

SqlDependency enables you to take action on a change to a database by executing a stored procedure. If a stored procedure is executed, it is stored in a SQL Server database table so that the next time that trigger is triggered, it can execute another stored procedure or update application code.

Basically this class is used when you have SQL Server trigger and you want to execute some code at the time of some update of SQL Server database.
If you dont want to use triggers, you can always use SqlDependency class, for that you need to use this code:
// Call this method to register a callback to the SqlDependency.OnChange callback method.
// Call it in the constructor of a class or a method.
public void RegisterChangeNotification(string source, DbCommandCallback callback)
// Replace the email and password with values that uniquely identify your server
if (!this.IsChangeNotificationEnabled())
this.SqlDependency.OnChangeCallback += new SqlDependency.OnChangeCallback(this.HandleSqlDependencyChange);
this.SqlDependency.OnChangeCallback += this.HandleSqlDependencyChange;

What’s New in the AutoCAD?

Embed your drawing in any work area. This feature allows you to create a sidebar window in your drawing that automatically updates whenever you make a change to your drawing. (video: 1:30 min.)

Embed arbitrary geometry. You can now embed geometry from any file type or from the web. (video: 1:10 min.)

Related objects snap to work space references, just like in AutoCAD 2019. (video: 1:15 min.)

Dimensioning and Hatch blocks:

Dimensioning is now more customizable. New objects make it easy to format blocks as rectangles, circles, or any shape. (video: 1:00 min.)

Hatch blocks now support dynamic hatch styles. You can dynamically define an opening based on blocks that make up your drawing, similar to dynamic wire. (video: 1:00 min.)

View and edit views:

Print views now support the ability to add text in your drawings. (video: 1:30 min.)

Set the current view to show only the selected views in the drawing. (video: 1:15 min.)

Document Now:

Delete the “Revision Level” option from the Document Now dialog. This helps users find the most recent version of a file more easily. (video: 1:40 min.)

Full text search now supports Boolean operators. You can search on multiple terms to find multiple variations of a string. (video: 1:15 min.)

User-defined commands:

You can now create a user-defined command to toggle between drawings and edit mode. You can specify the command to activate in the Drawing Template wizard. (video: 1:15 min.)

Set new-page view in layer and print navigation settings to “on top.” This option is now available in Print Settings and Layer Properties dialog. (video: 1:00 min.)

Add new-page view in Print Settings and Layer Properties dialog. You can now define a default setting to new pages in the Print Settings and Layer Properties dialog, to make it easier to print new pages for each layer. (video: 1:00 min.)

View-only data:

Edits in a view-only data document are now bound to layers.

Add a new option to the Attribute Info dialog to display the text properties of a view-only data document. (video: 1:15 min.)

System Requirements:

OS: Windows 7/8
Processor: Intel i5-3320 / AMD Phenom II X4 965 / AMD FX 8350
Memory: 8 GB RAM
Graphics: Nvidia GTX 560
DirectX: Version 11
Storage: 30 GB available space
Additional Notes: The loading times are not as long as those in previous games. However, even if you have a decent system you’ll be able to enjoy the game very easily.In the handling of plastic materials, for example, the manufacture of containers
