A)INTRODUCTION TO COMPUTER AIDED DESIGN(CAD) What is AUTOCAD?.CAD is a computer-aided tool that

allows many different types of designers to create diverse kinds of drawings and designs. This program helps designers create their designs much more quickly than by hand and offers many quick, easy, and useful features, such as copy and paste.Essential,it gives detailed description about any component in a graphical form.

 Engineering drawings have been in use for more than 2000 years. However, the use of orthographic projections was formally introduced by the French mathematician Gaspard Monge in the eighteenth century.  When it was introduced first, CAD was not exactly an economic proposition because the machines at those times were very costly. The increasing computer power in the later part of the twentieth century, with the arrival of minicomputer and subsequently the microprocessor, has allowed engineers to use CAD files that are an accurate representation of the dimensions / properties of the object

AII) EXAMPLE OF CAD SOFTWARE There are some softwares that are developed by CAD software.  2D CAD  3D CAD  3D WIREFRAME AND SURFACE MODELLING  SOLID MODELLING

With more and more companies (if not all) turning to CAD / CAE / CAM to achieve efficiency, accuracy and reduced timeto-market of products, there is a growing demand for CAD software. The industry leaders in this space include AutoCAD, Dassault Systems and Altair. Aiii) INTRODUCTION TO AUTODESK AUTOCAD SOFTWARE The company was founded in 1982 by John Walker, who was a co-author of the first versions of AutoCAD. Autodesk became best known for AutoCAD, but now develops a broad range of software for design, engineering, and entertainment and a line of software for consumers, including Sketchbook. It is supported by 750 training centres worldwide as of 1994.

As Autodesk’s flagship product, by March 1986 AutoCAD had become the most ubiquitous CAD program worldwide. As of 2014, AutoCAD is in its twenty-ninth generation, and collectively with all its variants, continue to be the most widely used CAD program throughout most of the world.

B)OBJECTIVE  Learn sketching and understanding field dimensions  Take data and use it to transform the data into drawings  Learn fundamentals of CAD drawing formats and commands  Learn basic AutoCAD skills.  Learn who draw 2D drawings in AutoCAD.  Understand the concept and techniques to draw.  Navigate throughout AutoCAD using major navigating tools.

E)CONCLUSION At the last, we arrived at the end of this course, clearly AutoCAD wont end here, there would be lots more to explain and we to learn more about the AUTOCAD design, but what about the basic functions of the program, we have already treated several topics on which you have to practice a lot and once you master you will be able to create and print your designs using this program.We are capable with the fundamentals and introduction of AUTOCAD design. Practice makes perfect.So,Practice a lot with the commands you have learned,try then to create something more elaborate and more tricky,more hard ,such as Plant,3D objects ,a furnished room or a technical drawing of an object,a brand etc.. according to your preferences and needs,you can draw in AutoCAD just about anything. When you start the designs calculate from the outset the scale factor with which they print, and scale the size of the template,the text and basic dimensions in according to this and the paper size you wish to use.you and can deepen more the potential of AutoCAD
