AUTO CAD TECHNICAL DRAFTING MODULES FOR GRADE 9 AND GRADE 10

ORIENTATION ABOUT HOW AUTOCAD STARTED

1. TECHNICAL DRAFTING PRESENTED BY: MAAM JAMAICA TRIXIA E. BRON

2. OPERATING CAD SOFTWARE AND COMPUTER HARDWARE

3. HARDWARE The physical equipment that makes up the computer system. SOFTWARE A set of programs and other related applications associated with a computer system

4. CENTRAL PROCESSING UNIT The brain of the computer where most of the “computing” takes place. CAD Software and Hardware Computer system can be broken down into basic elements, the hardware and the software.

5. The Hardware

6. SYSTEM UNIT- The main part of the microcomputer, or sometimes called chassis. It includes motherboard, microprocessor, memory chips, buses, ports, expansion slots and cards.

7. Keyboard Monitor Mouse Printer Hard disk drive (HDD)- a magnetic storage device that is installed inside the computer Optical Drive- a storage device that uses lasers to read data on the optical media.

8. Digitizer Tablet- is a graphic drawing tablet used for sketching new images or tracing old ones. Plotter - an output device able to produce better quality drawings as compared to printer, its speed is slower than the printer.

9. The Software

10. Operating System Software Provides various levels of interaction (interface) between he computer and the user, as well as between the computer and the application software.

11. Application Software Also called as programs, has specific use or task to perform such as AutoCAD for architectural drawings and layouts, Lotus 1-2-3 for business and marketing, Adobe Photoshop for image processing and so on.

12. ACTIVITY 4 Supply the Graphic organizer with the correct answer.

13. Introduction to AutoCAD

14. AutoCAD was one of the first Computer Aided Design programs to be made available on personal computers. It is built to help people design buildings, products, or public spaces, without having to draw up plans by hand.

15. It was released in 1982 by Autodesk , Inc., and offered a personal solution to software that was before then released only for larger workstations. AutoCAD is used for 2D and 3D design and technical drawing. Additional tools allow it to be used by architects and engineers .

16. A CAD system is a combination of hardware and software that enables engineers and architects to design everything from furniture to airplanes.

17. In addition to the software, a CAD system requires; • a high-quality graphics monitor; a mouse, light pen, or digitizing tablet for drawing; and • a special printer or plotter for printing design specifications.

18. CAD software CAD , or computer-aided design and drafting (CADD), is the use of computer technology for design and design documentation . CAD software replaces manual drafting with an automated process.

19. STARTING A N AUTOCAD

20. 1. FROM THE START MENU - Click Start >Programs > Autodesk> AutoCAD From The Windows Program Manager

21. 2. FROM THE DESKTOP SHORTCUT -Double click the A utoCAD icon from your desktop

22. 3. BY OPENING THE DRAWING FILE - Double-click the drawing file icon inside a folder or in any location from your computer.

23. The AutoCAD working Environment

24. The AutoCAD working Environment MENU BROWSER- a client software that lets users read or scan documents on the World Wide Web. QUICK ACCESS TOOLBAR- located along the top of the application window and provides direct access to common or defined set of commands like New, Open, Save, and Plot..

25. C. FILENAME- the name of the current file you are working on. D. MENU BAR- the horizontal strip across the top of an application’s window. E. SEARCH BOX- a tool that allows you to search for a particular data or document in help file or to web.

26. F. TOOLBARS/ RIBBON- provide a single, compact placement for operation/ tools that are relevant to the current workspace. COMMAND LINE BAR- is where you enter the commands from the keyboard and where the prompts 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.

27. I. UCS (USER COORDINATE SYSTEM) -Is found at the bottom left hand corner of the AutoCAD drawing window. J. WCS (WORLD COORDINATE SYSTEM) -By default when you start a new (blank) drawing you use the World coordinate system. This indicates your (0,0,0) point.

28. DRAW TOOLBAR- draws command can be used to create new objects such as lines and circles. Most AutoCAD drawings are composed purely and simply from these basic components. MODIFY TOOLBAR- used to modify the basic drawing objects in some way to suit the image you need. (move, copy, rotate, mirror) WORKING/ DRAWING AREA- a place where your drawings are displayed and modified.

29. N. CROSSHAIRS- 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.

30. P. DIALOG BOX LAUNCHER- displays the coordinate location of your crosshairs and the current setting of grid, snap and other drawing aids.

31. AUTOCAD COORDINATE SYSTEM

32. Coordinates fall into two types, namely Cartesian and Polar. They can be either Absolute or Relative. The Cartesian Coordinate System is the standard coordinate system. The position of a point can be described by its distance from axes, X and Y.

33. The Polar Coordinate System uses one distance and one angle to describe the position of a point rather than the two distances. The distance and angle measurements are made relative to an origin.
