7. HISTORY : The Interact CAD Package in 1970’s Developed by MIKE RIDDLE. In 1982, JOHN WALKER to developed Cad Software in California. 1984 – Auto Desk company has purchased from john walker and release in the name of A uto CAD. 7 CADD File Format: *. dwg - AutoCAD Drawing *. dws - AutoCAD Drawing Standards *. dwt - AutoCAD Templates

8. CAD Advantages Very high dimension accuracy. Time, cost, money save. Easy modification and draw. Less error. We can send Email. We can create password. Storage facility. User friendly software. 8

9. Users of CAD CAD is used by: Drafters Designers Engineers Architectural 9 Civil, Architectural Mechanical, Electrical, Marine, Aeronautical, Automobile, etc.,

10. ENGINEERING DRAWING TYPES: View based drawing. Dimension based drawing. Engineering language. 10

11. UNITS Decimel – mm, cm, m, km. Engg & Architectural – inches, feets . Scientific – light years. Fractional – micro inches . 11 Angle: Decimal Degree, Deg /Min/Sec, Grads, Radians, Survey Units Precision: Sets the number of Decimal places or fractional size displayed for linear Measurement Example: 0, 0.0, 0.00, 0.000

12. LIMITS Limits Sets an Invisible boundary in the Drawing Area by Specifying Lower left & Upper Right Corner of the boundary Initial : 0,0. Secondary : A0 - 841 x 1189 A1 - 594 x 841 A2 - 420 x 594 A3 - 297 x 420 A4 - 210 x 297 12

13. 13 Application Example: A0, A1 - Technical Drawings, Posters A2,A3 - Drawings, Diagrams, Large Tables A4 - letters, Magazines, Forms, Catalogues, laser Printer, Photocopying Machines A5 - Note Pads A6 -Postcards A6,A5,B6,B5 - Books C6,C5,C4 - Envelops for Letters: unfolded (C4),folded (C5),folded (C6) B4,A3 - Newspapers

14. CO ORDINATE SYSTEM It means flow to draw the drawing without using mouse,(only using keyboard) it is called co-ordinate system. 14 TYPE: 1.Absolute Co-Ordinate System. 2.Relative Rectangular Co-Ordinate System. 3.Relative Polar Co-Ordinate System.

15. ABSOLUTE CO-ORDINATE SYSTEM All points are Measured from the Origin ( 0,0 ). This Based on X,Y point. X – Horizontal Axis Y – Vertical Axis C: L (line) C:2,2 C: 2,8 C: 8,8 C: 2,2 C: 0,0 15 X Y

16. RELATIVE RECTANGULAR CO ORDINATE SYSTEM Based On The Last Point Entered. Use A Relative Co-ordinate When You Know The Location Of A Point In Relation To The Previous Point. This based @ X,Y Distance 16 a b x 0,0

17. RELATIVE POLAR CO ORDIANATE SYSTEM A Combination of Angle and Distance input is called Polar Co-ordinate System This based on @ Distance < Angle 17 x y 30
