Introduction to Autodesk AutoCAD

In this article, we will learn how to create a project in AutoCAD and export it to PDF or DTP format.

What is AutoCAD?

AutoCAD is a CAD design software that can be used for generating Construction drawings and technical design plans, such as mechanical drawings and blueprints. AutoCAD is an industry-standard integrated CAD software, used by many professionals worldwide in the engineering, architecture, construction, landscape architecture, and construction industries.

AutoCAD is usually used for creating architectural and engineering drawings, which are used for depicting the following:

Structures and buildings

Landscapes and landscapes

Electrical and plumbing systems and blueprints

Tools used in the construction and production process

AutoCAD is based on a vector-graphics design, which uses lines, curves, arcs, and splines to create 3D designs, whereas a raster graphics design uses raster (pixel) graphics.

Over time, AutoCAD has evolved from a simple tool into a highly advanced design application that can produce CAD files for several industries and multiple purposes. AutoCAD is also available in mobile and web versions to use on mobile devices.

AutoCAD is available for Windows and Mac computers and is either free or paid.

Requirements for using AutoCAD

In order to get started, we need to make sure that all the requirements are met before we start our AutoCAD project:

Operating system: Windows XP, Windows 7, or Windows 8

Hard Disk: 30GB of free disk space

Monitors: 1920×1080 at 60 Hz

Mouse: USB

Keyboard: USB


Internet connection

How to Install Autodesk AutoCAD

To Install the AutoCAD application, Download and extract the zip file.

After extracting the zip file, we will find the AutoCAD installation folder in C:\Program Files\Autodesk\AutoCAD

Locate the “AutoCAD.exe” file in the AutoCAD folder. Right-click on it and select “Run as administrator”.

Enter the folder path and click on the Run button. Click on Yes and the installer will be launched. Click on Install. After a successful installation, we need to restart the computer and launch the AutoCAD application.



Autodesk also offers the AutoCAD Extension Environment (A.E.E.), which allows a user to extend the base capabilities of AutoCAD, using the AutoCAD API.


With the release of AutoCAD 2010 a brand new graphics engine was developed. This engine allows the inclusion of 3D objects in drawings, as well as 2D animation and video support. Other features include automatic sizing of text, drawing fills and other elements based on the dimensions of the objects.

With AutoCAD 2009, the Graphics View Engine (GVE) was replaced by Autodesk’s new Ray Tracing Engine (RTE).

The Ray Tracing Engine was first introduced in AutoCAD LT 2007. It uses three basic types of rays: shadow rays, view rays, and diffuse rays. View rays and diffuse rays are just what they sound like, they are meant to interact with the user’s view of the 3D environment. Shadow rays, however, have a different purpose. The shadows cast by objects represent the thickness of the objects. This means that shadow rays are always bounced between surfaces until they exit the model. After the view rays and diffuse rays have interacted with surfaces, they are bounced between surfaces in order to detect if any shadow rays pass through. This is done because the depth values provided by the shadow rays are only accurate when they are cast from the perspective of the viewer.

In addition to object-based ray casting, AutoCAD also supports per-object ray casting. In this mode, surface- and volume-based ray casting can be enabled, in addition to shadow ray and view ray casting. Surface-based ray casting is useful for a wide variety of tasks, such as turning on or off lighting and adding texture. Volume-based ray casting is useful for determining the size of objects in order to perform implicit solid sizing and calculating the intersections of light rays with solids. For example, determining if a given object cast a light ray into the camera.

Ray casting is important to AutoCAD’s ability to generate detailed 3D models. Ray casting is a computationally expensive operation, however, the ability to perform it at the user’s discretion allows users to disable ray casting when they require more computational performance. The ray tracing engine is also scalable. AutoCAD can run ray tracing at many times the speed of pre-2007 implementations.

RTE can also be enabled and disabled independently of the GVE. This allows users to have the full power

AutoCAD Keygen

Open the Autocad Autodesk software you bought at the beginning of this page.

Use the Autocad Autodesk software
Press the Microsoft Windows key + R or the key combo to open the Run window.

In the window that opens, type the following:
regsvr32 “c:\Program Files\Autodesk\AutoCAD 2011\Acad.inf” /s /i


Autocad Autodesk software:

Install the Autocad Autodesk software from your Autodesk Autocad Autodesk software from the setup folder.

Program files:



Press the OK button.

The.inf file has been installed in the location you specified.

You can now open Autocad Autodesk software and use it.

Note: The use of the file ‘Acad.inf’ has several drawbacks:

– Every time the license is renewed, you must repeat the process of registering the software and run the above command.

– The.inf file will be automatically updated by Autodesk Autocad Autodesk every time there is a change in the software (in most cases, that is about once a year).

– The.inf file may become incompatible with new Autocad Autodesk software releases.

Defective hybridization of MHC class II-encoding sequences among intra-familial HLA identical sibling pairs: segregation with HLA-DRB1 alleles.
We have investigated the mechanism of HLA class II cross-matching in four intra-familial HLA-identical sibling pairs. In all cases, the immune response to the family donor was responsible for loss of the HLA cross-match. Comparison of the class II genotypes and DRB1 alleles of these four donors and their family donors did not reveal any shared haplotypes or identical combinations of alleles. Rather, each donor showed a unique combination of DRB1 alleles and class II haplotypes. Furthermore, a single or double mismatch in either the DRB1 or the DQ region was often present. The observed discrepancies in antigen presentation may be caused by genetic polymorphism of class II DQ region genes that either influence antigen presentation or have arisen after gene-crossover during sexual reproduction.
