ORTHOGRAPHIC PROJECTION ...ppsx
- 1. 5 Orthographic projection is a parallel projection technique in which the parallel lines of sight are perpendicular to the projection plane MEANING Object views from top Projection plane 1 2 3 4 5 1 2 3 4
- 2. Orthographic projection technique can produce either 1. Multiview drawing that each view show an object in two dimensions. 2. Axonometric drawing that show all three dimensions of an object in one view. Both drawing types are used in technical drawing for communication. NOTES ORTHOGRAPHIC VIEW
- 3. Axonometric (Isometric) Drawing Easy to understand Right angle becomes obtuse angle. Circular hole becomes ellipse. Distortions of shape and size in isometric drawing Advantage Disadvantage Shape and angle distortion Example
- 4. Multiview Drawing It represents accurate shape and size. Advantage Disadvantage Require practice in writing and reading. Multiviews drawing (2-view drawing) Example
- 5. ORTHOGRAPHIC PROJECTIONS: Horizontal Plane (HP), Vertical Frontal Plane ( VP ) Side Or Profile Plane ( PP) Different Reference planes are FV is a view projected on VP. TV is a view projected on HP. SV is a view projected on PP. And Different Views are Front View (FV), Top View (TV) and Side View (SV) IT IS A TECHNICAL DRAWING IN WHICH DIFFERENT VIEWS OF AN OBJECT ARE PROJECTED ON DIFFERENT REFERENCE PLANES OBSERVING PERPENDICULAR TO RESPECTIVE REFERENCE PLANE
- 7. Orthographic Projections are a collection of 2-D drawings that work together to give an accurate overall representation of an object. Defining the Six Principal Views or Orthographic Views engineering108.com
