An easy approach towards understanding projection of lines.
The projection of a line can be obtained by projecting its end points on planes of projections and then connecting the points of projections. The projected length and inclination of a line, can be different compared to its true length and inclination.
Case 1. Line parallel to a plane
Case 2. Line inclined to a plane
VP:The plane in front of observer is the vertical plane. (VP)or it is also called a Frontal plane.
Front View (FV):The projection on the VP is called the Front View (FV)or Vertical Projection or front elevation or Elevation.
HP:The plane which is Horizontal and perpendicular to VP is Horizontal Plane.
Top View (TV):The projection on the HP is called the Top View (TV)or Horizontal Projection or Plan.
Note:The planes HP and VP are called Principal Planes.
Reference Line:The line of intersection of HP and VP is called reference line, which is denoted by X-Y.
