A site plan is an engineering and architectural drawing of a lot, to show the details of any changes on the lot or any improvements. A site plan usually includes a building footprint, travel ways, parking, drainage facilities, sanitary sewer lines, water lines, trails, lighting, and landscaping and garden elements.
A floor plan is a scale diagram of the arrangement of rooms in one story of a building.
A zoning plan is a map of the separated properties and lands , and is usually used by local governments.
A city plan, is a map of a city to show which is drawn to show such information as the present and the future growth of a city.
An elevation is a view of a building form one side, used to describe the external appearance of the building from each side. Each elevation is labelled in relation to the compass direction it faces.
The technique called section views is used to improve the visualization of new designs, clarify multi-view drawings and facilitate the dimensioning of drawings.
Isometric is a method used to show 3 dimensional drawings in 2 dimension, in a way that all horizontal lines are drawn at 30 degrees to the base line.
Axonometric is a method used to show 3 dimensional drawings in 2 dimension, in a way that all horizontal lines are drawn at 45 degrees to the base line.
1 Point Perspective:
1 Point Perspective is an approximate representation, on a flat surface (such as paper), of an image as it is seen by the eye. In one-point perspective, only one vanishing point exists; lines radiate outwardly from this point, and perpendicular lines meet at this point. One-point perspective is the same as parallel perspective.
In two-point perspective, there exist two points from which an object’s lines radiate from; the sides of the object vanish to one of two vanishing points on the horizon line. An object’s vertical lines do not relate to the perspective rules of the horizontal lines. By changing the vanishing points of the object, one can make increase or decrease the size of the object. Two-point perspective is the same as angular perspective.
