AutoCAD Crack History

AutoCAD R12 was introduced in 1989 and used a new type of vector-graphics technology. This was a significant departure from previous vector-graphics products, as previous tools required raster-graphics techniques. R12 incorporated a new feature, the Dynamic Input Manager (DIM), which facilitated the input of moving objects such as drafting parts on to a planar or non-planar surface. AutoCAD R13 was released in 1992. AutoCAD R14 was released in 1996 and AutoCAD R15 was released in 1998. AutoCAD 2000 and AutoCAD LT 2000, released in 1999, introduced the ability to draw objects directly on the screen, which could then be converted to 3D views. AutoCAD 2002 was released in 2001 and AutoCAD 2003 in 2002. AutoCAD 2004 was released in 2003 and AutoCAD 2010 was released in 2009. AutoCAD 2013 was released in 2011. AutoCAD 2015 was released in 2012 and AutoCAD LT 2015 in 2013.

AutoCAD Key Features

Note: If you experience problems with installing, uninstalling or using AutoCAD, see the documentation or contact AutoCAD’s Customer Support Center for assistance.

Features Overview

AutoCAD has a wide range of features that can be used in a variety of ways, and these are discussed in more detail under “Using AutoCAD.”


Draw lines, shapes, or solids (geometric solids, geometric surfaces, and solid volumes).

Repetitive drawing tasks such as dimensioning and labeling are easily automated using the drawing tool functionality.

Draw traditional wireframes with fillets and chamfers, using the Insert⇒Solid or Object⇒Dimension tool.

Create splines and polylines in 2D and 3D viewports.

Insert AutoCAD DWG (drawing) files. These are also known as.dwg,.dxf, or.dwgx files.

With the command feature, you can draw an entire drawing from beginning to end. You can also use the command feature to capture portions of drawings.

Extend drawing functions with custom functions.

Easily change object colors in 2D or 3D viewports.

Easily rotate, mirror, and reverse objects in 2D or 3D viewports.


AutoCAD Free

The first versions of AutoCAD appeared in the 1980s and were originally in 4 and 5 user interface and later in 3.0 they were available only in one user interface.

In 1990, Autodesk released AutoCAD LT, designed to run on lower-end systems such as Windows 9x, 98 or NT.

AutoCAD 2000, released in 1999, replaced its AutoCAD 1992 predecessor (and AutoCAD LT 1994) with a new 3D user interface. In 2000 Autodesk added the product symbol number “1990” to all software applications, and began using this number to denote the year in which the software version was released, with exception of the 2016 year release. AutoCAD 2007, released in 2006, has been the last Autodesk release to use the “1992” number.

In 1998, the company released Autodesk Architectural Desktop (ADT), which was renamed to AutoCAD Architecture in 2000.

In 2000, Autodesk acquired ComponentWare. ComponentWare had released Component Technology for its CAD products in 1995, and would later be acquired by Autodesk in the same year.

Development environment

AutoCAD is primarily developed on the Windows platform. There are various “build environments” for developers:

AutoCAD 2010 includes a multi-threaded 64-bit Windows Forms and WPF environment.


AutoCAD has two primary modes of licensing: one for individuals and one for organizations. Individual licensing is primarily used for academic and private users. A student working in a private or public school can receive a free license by using their school’s email address.

Licensing for organizations is designed to provide corporate users, and businesses with multiple offices, with the ability to license and sell subscriptions (subscriptions are now available for AutoCAD 2012). The types of subscriptions available include:

A free trial of AutoCAD is offered to all customers and can be downloaded from the Autodesk website.

AutoCAD’s primary user base is CAD engineers, architects and other related industries (such as GIS, water resources, construction, and engineering). The second largest user base of AutoCAD is the mobile phone industry.

Popular applications
AutoCAD is used for design and drafting in a variety of fields, including architecture, engineering, medicine, and petroleum, as well as manufacturing and production.

These industries include:

AutoCAD Crack + Free

Install the keygen.

Download the installation files of Autodesk Autocad (they will be in the form of zip files)

Unzip and upload all the files to a folder.

Registering your license

First, you need to have an Autodesk account. If you don’t have one, please create one here.

After that, you need to register your license by following these steps:

Open Autodesk Autocad by clicking on the Start menu and select Autodesk Autocad or by typing Autodesk Autocad in the search bar.

When the program opens, on the top left corner, click on the icon with the Manage license button.

On the page that will open, click on the Register License button.

Put the information of your license.

You can now close Autodesk Autocad and continue to read the article.Q:

How to change the primary key of the table to a non-nullable field?

I need to change the primary key from (Id) to a non-nullable field. I am using entity framework code first approach for that.


Use DataAnnotation:
public int Id { get; set; }

If you want change Id field as not nullable, add parameter to IDataBaseGeneratable interface.
If you use PostgreSQL,


EF can use both Identity columns and NOT NULL columns as PKs. If you want to make this PK nullable, then use the DatabaseGeneratedPattern attribute.

In.Net Core, you can use this code


Get user from Facebook API

I know it’s possible, but I have problem.
I have this code:
$config = array();

$config[‘appId’] = ‘xxx’;
$config[‘secret’] = ‘xxx’;
$config[‘fileUpload’] = false;
$config[‘fileUploadExtraData’] = array(
‘appSecret’ => ‘xxx’

$facebook = new Facebook($config);


What’s New in the AutoCAD?

Update: The updated 2019 version of AutoCAD is now available. The 2023 release schedule will be re-announced in November 2019.

Markup tools:

Use the Markup toolbar to add and edit text or annotations for nearly any object. (video: 1:31 min.)

Easily draw freehand annotations such as arrows, arrows with curves, and text on all shapes and text objects. (video: 1:36 min.)

Work more comfortably with floating annotations: create, resize, and position them freely without touching the drawing itself. (video: 1:50 min.)

Add more visibility to drawings: the default highlight color is now more visible against the white background. (video: 1:15 min.)

Extended FEM:

FEM (Finite Element Method) is a powerful tool for finding the mechanical behavior of a structure by solving stress and strain equations.

FEM can be used to find stress and strain distributions, or to predict the mechanical behavior of a 3D model under an applied load. The model can be as simple or complex as you need.

Evaluating and updating the FEM model is easy. You can:

Achieve a better understanding of your design.

Test your assumptions.

Have more confidence in the results.

Export the analysis data to files such as DXF and JPG.

Use FEM to evaluate the mechanical behavior of real-world structures, such as a bridge or high-rise building.

The updated 2019 version of AutoCAD is now available. The 2023 release schedule will be re-announced in November 2019.

FEM tools:

Explore the surface of 3D models and surfaces with this new FEM tool. Apply smoothing, use colors, and search for the creases and folds. (video: 1:36 min.)

Test mechanical behavior with a stress analysis.

Import and export analysis data. (video: 1:35 min.)

Advanced ray casting:

Automatically raycast light into a 3D model.

Interact with the light rays and spot the shadow effects.

Specify any shape of light source and light settings.

Automatically generate a shadow map for the model. (video: 1:26 min.)

Raycast faces, edges, and 3D objects. (video: 1:29 min.)

System Requirements:

Online Multiplayer.
Windows (OSX supported).
At least 2GB of RAM (More is better).
