  1. Forging new generations of engineers

  2. Engineering Drawing Types

  3. Basic Engineering Drawing Types • 1. Freehand Sketch (2D or 3D) Anything goes Can be 2D or 3D Can be rough and quick or neat, detailed and shaded No tools are used (rulers, protractors, stencils, etc.) • 2. Pictorial Drawings (3D) • Isometric drawings 2. Oblique drawings 3. Perspective drawings • Orthographic Drawing (2D) • Orthographic Projection Drawing (Multi-view Drawings)

  4. Freehand Sketch

  5. Sketching • Pros - Most used, easy, quick, can be used anytime and anywhere • Cons – no set format

  6. Purpose of Engineering Drawings (instead of sketching) • Universally accepted • From department to department within a company • From one company to the next • And even from country to country • Efficient • Drawing gives more information at faster rate then trying to explain it • Save time and money • Multi-functional • Can be used simultaneously in all departments • Design, drafting, prototyping, production, and advertising

  7. Stop here

  8. Advanced Engineering Drawings • Renderings • Auxiliary • Sections • Assembly • Exploded • Animation

  9. Rendering Pictorial Drawing

  10. Auxiliary Drawing • TLs • True Lengths • 90

  11. Section Drawing • Cutting Plane • View remaining part from this direction • Ortho view of sectioned part • Solid Material • Removed Part

  12. Assembly Drawing

  13. Exploded Drawing • Balloons • Parts List

  14. Animation Video
