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…

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

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

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

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)

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.
