This document discusses the key elements and types of perspective drawings. Perspective drawings are important for architects and clients because they provide a view of a building or town that closely approximates human vision. Key elements discussed include the ground line, station point, vanishing point, and picture plane. Perspective drawings are classified as parallel perspective, one point perspective, angular perspective, two point perspective, or three point perspective depending on the number of vanishing points used.

- 7. Vanishing point (VP) • The topical characteristics feature of a perspective drawing is the vanishing of all parallel lines of object to a point at infinite distance. • The point at which a parallel lines of the object was inclined to the picture plane and appears at that points is known as VP.
- 8. Picture plane • It is a imaginary transparent plane between building and observer on which the image of the building is projected and perspective is drawn.
