PLAN
, a representation of something, drawn on a plane. Such as maps, charts, and ichnogrophies.
Plan, in Architecture, is particularly used for a draught of a building; such as it appears, or is intended to appear, on the ground; shewing the extent, division, and distribution of its area into apartments, rooms, passages, &c. It is also called the Ground Plot, Platform, and Ichnography of the building; and is the first device or sketch the architect makes.
Geometrical Plan, is that in which the solid and vacant parts are represented in their natural proportion.
Raised Plan, is that where the elevation, or upright, is shewn upon the geometrical Plan, so as to hide the distribution.
Perspective Plan, is that which is conducted and exhibited by degradations, or diminutions, according to the rules of Perspective.
