INTRODUCTION TO AUTOCAD

Also Read

AutoCAD is a program designed for draw the drawings, for example in mechanical engineering, civil engineering and surveying. There can be two-dimensional design drawings in terms of (2D) and three-dimensional view (3D) in the case (drawing), which lines.
Working in AutoCAD requires some basic knowledge of your work, and also good to have prior knowledge base and knowledge of the plot coordinate system.
AutoCAD is a low cost yet very effective computer aided design and drafting software.

Some of the advantages of CAD over manual drawing are:

  • No need for scaling. We can create all drawings  in full size.
  • The screen drawing area can be set to any size with the click of a button.
  • The program supplies all of the tools needed.
  • Absolute accuracy can be maintained.
  • Production details can be extracted directly from the drawing.
  • Eliminates the need for full size set outs.
  • Both two and three-dimensional drawings can be produced.
  • Your work is copied and store off the computer for security – you may never lose your work again.
  • Drawings are stored on disk rather than in a bulky folder.
  • Dimensioning is almost automatic.
  • Parts of drawings can be saved and used in other drawings.

    Starting up AutoCAD

    If you install AutoCAD 2008 using default settings for the location of program file, start AutoCAD by choosing
    Start ⇒ Programs ⇒ Autodesk ⇒ AutoCAD 2008
    Or
    double click on AutoCAD 2008 Icon on your desktop

    AutoCAD 2008 Interface


    Menu Bar: Contains the default AutoCAD menus.

    Standard Toolbar: This contains the frequently used buttons such as Zoom, Undo and Redraw. It also has the Microsoft Standard buttons.

    Drawing tools and modify toolbars: These toolbars provide you with the common draw and modify commands.

    Cross-hairs: The cross-hairs are controlled by the mouse, to locate points and select and draw objects.

    Command window: The command window displays messages and prompts.

    In AutoCAD there are three ways of initiating commands.
    1. Click a button on a tool bar
    2. Choose an item from a menu.
    3. Enter the command on the command line.

    Isometric drawings for practice in AutoCAD

    What is Isometric Drawing? Isometric drawing is a method of visually representing three-dimensional objects in two dimensions. It allows for a clear and comprehensive depiction of complex structures by keeping the scale consistent and eliminating distortion. Isometric drawings use a 30-degree angle from the horizontal in all three axes (X, Y, and Z), creating a pseudo-3D effect where the height, width, and depth are equally foreshortened. Creating Isometric Drawings in AutoCAD AutoCAD provides tools and settings that make creating isometric drawings straightforward. Here’s a step-by-step guide: Step 1: Set Up Isometric Snap/Grid 1. Enable Isometric Snap/Grid:    - Type `SNAP` in the command line and press `Enter`.    - Type `Style` and press `Enter`.    - Choose `Isometric` and press `Enter`. 2. Switch Between Isoplanes:    - Type `F5` or `CTRL+E` to toggle between the top, right, and left isoplanes. Step 2: Draw Isometric Circles and Arcs 1. Isom...

    Fluid mechanics VIVA QUESTIONS and ANSWERS

    1. Define density? Ans: It is defined as the ratio of mass per unit volume of the fluid. 2. Define viscosity? Ans: It is defined as the property of fluid which offers resistance to the movement of fluid over another adjacent layer of the fluid. 3. Differentiate between real fluids and ideal fluids? Ans: A fluid, which is in-compressible and is having no viscosity, is known as ideal fluid while the fluid, which possesses viscosity, is known as real fluid. 4. What is a venturimeter? Ans: It is a device which is used for measuring the rate of flow of fluid flowing through pipe. 5. What is a notch? Ans: A notch is a device used for measuring the rate of flow of a fluid through a small channel or a tank. 6. Define buoyancy? Ans: When a body is immersed in a fluid, an upward force is exerted by the fluid on the body. This upward force is equal to the weight of the fluid displaced by the body. 7. Define meta-centre? Ans: It is defined as the point about which a body...

    Sheet metal Funnel making

    Making a Funnel using metallic sheet Making a Funnel using metallic sheet Aim:- To make a funnel from a given (GI)metallic sheet. Tools Required:- MALLET, SNIP, STAKE, STEEL RULE, BALL PEEN HAMMER, STRAIGHT EDGE, RIVETS, SCRIBER Procedure:  The size of the given sheet metal is checked for its dimensions using a steel rule The required development of surface is being made on the white paper which is overlapped on the sheet metal. The marking is done on the sheet metal as per the development being done on the paper. Now using straight snips, unwanted materials are removed. Now fold and bend the workpiece to make the funnel shape and joint is made on the workpieces. Then using a groover, a locked grooved joint is made for about 5mm. Also, hemming is done in the bottom of the funnel. In between top face and bottom face, a butt joint is made using a solder. Finally, trimming and finishing operations are carried out. Safety Precautions:- Each cut you make exposes s...
