5 Questions
Define orthographic projection and explain its key features.
Orthographic projection is a technique used in technical drawing where projectors are parallel to each other and perpendicular to the plane. Ortho means perpendicular, and graphics means right angle drawing. Different views of an object are projected on different reference planes observing perpendicular to respective reference plane, with the main reference planes being Horizontal Plane (HP), Vertical Plane (VP), and Side or Profile Plane (PP).
What are the different views and notations used in orthographic projection?
The different views and notations used in orthographic projection include Front View (FV) projected on VP, Top View (TV) projected on HP, and Side View (SV) projected on PP.
What are the two projection systems mentioned in the text and which countries use them?
The two projection systems mentioned are the first angle system used in European countries as per ISO standard, and the third angle system used in Canada, USA, Japan, and Thailand.
What is the role of the plane of projection in orthographic projection?
The plane of projection is the plane used for the purpose of projection in orthographic projection. It is where different views of an object are projected, and its orientation determines the type of projection system used.
Explain the significance of the term 'orthographic' in orthographic projection.
The term 'orthographic' in orthographic projection signifies that the projectors are perpendicular to the plane and parallel to each other, resulting in right angle drawing and projection of different views of an object on different reference planes.
