Were you able to explain the purpose of using CAD in your drawings? If you explained it well, Congratulations! You may now proceed to the next lesson. If not, you may ask the help of your parents, brother or sister. BRIEF INTRODUCTION Computer-aided design (CAD), also known as computer-aided drafting and design (CADD), is the use of computer systems to assist in the creation, modification, and analysis of a design. It describes the process of creating technical drawings with the use of computer software. CAD software is used to increase the productivity, to improve the quality of design, and to create a database for manufacturing. AutoCAD An AutoCAD is a commercial product made by Autodesk, with many versions, including one called AutoCAD Architecture. AutoCAD Architecture has purpose-built features specifically designed for architectural drafting. AutoCAD can maintain precise dimensional spacing among components such as walls, beams, columns, and doors. AutoCAD Architecture offers a library of pre-built components to help speed up and automate the design and construction process. 3 Starting an AutoCAD There are several ways of launching the AutoCAD program, depending on the preferences and condition you may want to begin. Follow each of the illustrated steps below: 1. From the Start Menu - Click Start >Programs >Autodesk >AutoCAD from the Windows Program Manager 2. From a desktop shortcut or quick launch toolbar. - Double-click the AutoCAD icon from your desktop 3. By opening the drawing file. - Double-click the drawing file icon inside a folder or in any location from your computer. The AutoCAD Working Environment Like other windows-based applications, AutoCAD comes with a wide- range of features used in many different aspects of a working drawing. A B C D E F J Crosshair K L Main Work Area I H G A. Menu Browser – is a client-software that lets users read or scan 4  documents on the World Wide Web. B. Quick Access Toolbar - is located along the top of the application window (above or below the ribbon) and provides direct access to common or defined set of commands like New, Open, Save, and Plot. C. Filename - The name of the current file you are working on. D. Menu Bar – is the horizontal strip across the top of an application’s window. Each word on the strip has a context sensitive drop-down menu containing features and actions that are available for the application in use. E. Search Box – is a tool that allows you to search for a particular data or document in a help file or to web. F. Toolbars/Ribbon - provide a single, compact placement for operations/tools that are relevant to the current workspace. By default (in its original setting), it contains the Standard, Layers, Properties and Styles toolbars. G. Command Line Bar - is where you enter the commands from the keyboard and where the prompts are displayed. It has a text area where all the previous commands are displayed. H. Tray Settings/Info Bar - quickly search for a variety of information sources, access product updates and announcements, and save topics in the Info Center. I. UCS – is found at the bottom left hand corner of the AutoCAD drawing window. You will see a symbol like the one shown on the right. This is called the UCS (User Coordinate System) icon and it is there to remind you which is the X axis and which is the Y axis. J. WCS - By default when you start a new (blank) drawing you use the World Coordinate System (WCS). This indicates your (0,0,0) point. K. Draw Toolbar - Draw commands can be used to create new objects such as lines and circles. Most AutoCAD drawings are 5  composed purely and simply from these basic components. L. Modify Toolbar – is used to modify the basic drawing objects in some way to suit the image you need. AutoCAD provides a whole range of modify tools such as Move, Copy, Rotate and Mirror. M. Working/Drawing Area – is the place where your drawings are displayed and modified. N. Crosshairs – is a type of cursor consisting of two lines that intersect and are used to locate points and selects objects in your drawing. O. Status Bar - displays the coordinate location of your crosshairs and the current settings of grid, snap, and other drawing aids. P. Dialog Box Launcher - displays the coordinate location of your crosshairs and the current setting of grid, snap, and other drawing aid ACTIVITY Activity # 1 Fill in the crossword puzzle by identifying the statements below. Match the number of the sentence to the boxes placed across or down the grid. Write your answer in your quiz notebook. 3 4 1 2 5 DOWN ACROSS 1. Displays the coordinate location 2. It is used to create new objects of your crosshairs and the current such as lines and circles. settings of grid, snap, and other drawing aids. 4. It is there to remind you 6  which is the X axis and Y axis. 3. It is used to locate points and 5. The place where your selects objects in your drawing drawings are displayed and modified. Activity # 2 Directions: Label the parts of the AutoCAD Windows. Write your answer in your quiz notebook.. CHECKING YOUR UNDERSTANDING Task 1: Guide Questions 1.
