Architectural Lines

architectural drawings contain information about size, shape, and location of all parts of the house
  • uses lines, symbols, views, and notes to convey ideas


architectural lines are drawn in proportion to size (half size: half as large as the house its drawn to scale)

½ = 1 foot = ¼ inch


drawings can be produced by the diazo process, creates prints that have dark lines on a light background


to communicate the type and quantity of the materials of the house, specifications are used to give directions of their use


to help produce blueprints, CADD (computer-aided drafting and design) is a program that develops house plans


because everyone that is involved in the house planning process must have their own copy of the drawing of the house, they carry prints with them, which are copies of the original architectural drawing.
