  1. ME5372/7372 Introduction to CAD/CAM Session 3,(September 04, 2008) Instructor : Rajeev Dwivedi www.engr.smu.edu/~rdwivedi/ME5372.html Department of Mechanical Engineering Southern Methodist University Dallas TX

  2. Communicating design for manufacturing • Communicating design what does it mean – To pass on the information such as • Part geometry • Dimensions • Tolerances • Material to be used • Processes • etc…

  3. Communicating geometry - Orthographic Projections • Usually/traditionally two dimensional media (paper/blueprint) used to communicate

  4. Communicating geometry - Orthographic Projections • Three dimensional object is projected onto two dimensional planes.

  5. Communicating geometry - Orthographic Projections • Sometimes axonometric views are included for better visualization/understanding of the geometry.

  6. Communicating geometry - Orthographic Projections Sometimes axonometric views are included for better visualization/understanding of the geometry.

  7. Orthographic Projection planes I: above H, in front of F(V) II: above H, behind F(V) III: below H, behind F(V) IV: below H, in front of F(V)

  8. Projection in Different Quadrants

  9. In third angle Projection • the view from the front is in the middle • the view from the left is on the left • the view from the right is on the right • the view from the top is on the top • the view from the bottom is on the bottom • the view from the rear is on the far right.

  10. Projection Quadrant Symbol

  11. Engineering drawing and Its components

  12. Solid Modeling with ProE

  13. ProE Interface

  14. Model Tree Structure
