PROJECT CAD-C

(COMPUTER AIDED DESIGN IN ‘C’)

Under the guidance of:Ms.SARU BAJAWA

INTRODUCTION TO CAD • Cad is Computer Aided Design • A combination of art and science with business application in the architectural or engineering fields

Overview Of CAD

• Designing products at a computer terminal or Work Station • Design engineer develops rough sketch of Product • Uses computer to draw product design before actual product is made.

BENEFITS OF CAD

• Shorter design time • Preciseness • New capabilities • Improved product quality • Reduced production costs

DRAWING A means for communication Design is used to relay a visual concept Safety Line Quality Texture Shape Tolerance

Proportion Elements

Efficiency Durability

Functionality Maintenance Consideration

FEATURES OF GRAPHICS PROGRAMMING • All video games, animation, multimedia, predominantly works using computer graphics. • A major use is in engineering and architecture system as automobile, aircraft design. • 2-D bar chart and pie chart linked to geographical chart.

Features Of The Project DRAW:. Line- draws line . . . . . .

Box- draws box Circle- draws circle Ellipse- draws ellipse Arc- draws arc Freehand- freehand drawing Text- write text

Contd.. Edit:. Wipe- clears screen . Erase- clears selectively . Move- moves selectively . Copy- copies selectively . Paint- paints the object

Contd.. File:-

. Save – saves current drawing . Loads- loads saved files . Print- prints current drawing

Contd.. Line Style:. Solid_fill – solid line . Line_fill – dashed line . Wide_dot_fill – dotted line . Close_dot_fill – closely dotted line

Contd..

Exit:. Exit from CAD
