- 2. GE8152- ENGINEERING GRAPHICS UNIT-1 ORTHOGRAPHIC PROJECTION In orthographic projections, the principle views – Front view, Top view, & Side views of an object are drawn by the direct observation. These views are drawn from the pictorial view of an object. The pictorial view is a three dimensional representation. By observing pictorial view, it is very easy to visualize the shape when the object is viewed from front, top & sides. Multi-view drawings provide the most accurate description of 3D objects and structures for engineering, manufacturing, and construction requirements
- 3. GE8152- ENGINEERING GRAPHICS UNIT-1 ORTHOGRAPHIC PROJECTION In engineering, there are two systems of projection: First Angle Projection – Europe, Asia and former European colonies in Africa and parts of Australia Third Angle Projection – Used in the USA and Canada, in Africa where American development is taking place and parts of Australia
