AUTO CADD PPT.pptx

  1. 1. AUTO CADD By Pravin kumar
  2. 2. INTRODUCTION  The word AutoCAD is made up of two words Auto (logo of company) & CAD(Computer Aided Design)  Its an 2D & 3D Software Developed by Autodesk company  Autodesk is U.S.A based company
  3. 3. Advantages of Autocad  Quickly create designs  Improved quality over hand drafting  Easily Modify  More Accuracy  Easy to transfer  Long time save
  4. 4. Career Option  Drafting Professional  2D & 3D Plan Developer  CAD Engineer (civil , Electrical & Mechanical)  Architecture and Interior designing
  5. 5. Auto cad screen
  6. 6. How Auto cad works  There is a co-ordinate system used in AutoCAD.  Every drawing shows its co-ordinate.  In above next slide the line shows its co-ordinate that is ( 9,6 ) & (-10,-4).  There is so many commands like copy, move ,rotate ,mirror in 2D, path array , rectangular array, polar array & more  Different types of drawing can be made in the same time by using a command that is LAYER.  Using line , arc , circle , rectangle , ellipse & polygon , so many drawing of different type can be made
  7. 7. Co-ordinate system  Every thing that we draw in AutoCAD is exact.  All object drawn on screen is based on simple X-Y co-ordinate system.  In AutoCAD it is known as world co-ordinate system (WCS).  We are drawing a line, so we have two points A(-10,-4) and B(9,6). As shown in figure
  8. 8. Tool bar  DRAW TOOLBAR AND MODIFY TOOLBAR :  Following image shows two very basic tool bars, these will be heavily used as you progress towards the end of your drawing. You can access these tool bars under Home tab.
  9. 9. Tool bar  Dimension Tool bar AutoCAD provides a whole range of dimensioning tools which can be used to quickly dimension any drawing without the need for measurement. Dimensioning in AutoCAD is automatic; lines, arrows and text are all taken care of by the dimension commands. AutoCAD dimensions are special blocks which can easily be edited or erased as necessary. AutoCAD provides lots of control over the way dimensions look. Using a system similar to text styles, dimension styles allow you to design dimensions so that they look just the way you want them to
  10. 10. How to set drawing units  To set the drawing units, go to the drop down window at the top let side of the AutoCAD 2013 screen labeled as Format or just press Alt + o key to do so. And from this menu select units. A pop up window will appear that will set our drawing units as shown below.
  11. 11. TEXT COMMAND IN AUTOCAD  Type the shortcuts like Line shortcut is L and (enter or space)  Type in command line  Search the icon under tool bar section line Symbol to pick up and use the tool
  12. 12. Editing  COPY  MOVE  MIRROR ARRAY SCALE STRETCH  OFFSET  ROTATE
  13. 13. Poly line  The PLINE command creates a chain line with multiple vertexes and straight or circular segments between the vertexes  Draw a closed shape with the pline command:  Then type PEDIT (polyline edit) on the command line and see what you can do with it: Enter an option [Close/Join/Width/Edit vertex/Fit/Spline/Decurved/Ltype gen/Undo]: Try Width and Spline
  14. 14. HATCHING  Hatching is used to add shaded patterns to objects and shapes within an AutoCAD drawing. Hatch patterns can be used to indicate a material to be used, such as a concrete hatch. Alternatively it could be used to make an area of a drawing stand out.  You will pick: ⚫ Pattern ⚫ Scale ⚫ Angle ⚫ points
  15. 15. Basic Shortcuts
  16. 16. 2D shortcuts
  17. 17. Auto cadd single line and double line drawing • Single line Drawing
  18. 18. TWO ROOM PLAN
  19. 19. Basic level
  20. 20. Advance level
  21. 21. Basic paper size
  22. 22. Thank you
