• AutoCAD computer aided drafting, helps
  designers prepare drawings, specifications, parts
  lists, and other design-related elements using
  special graphics, it is a calculations-intensive
  computer programs.
• Elevation view a drawing or design that
  represents an object or structure as being
  projected geometrically on a vertical plane
  parallel to one of its sides.
• RL RL is a acronym for Reduced Level, it is a
  term used in surveying and construction. It is a
  value taken from a fixed point to reduce errors
  as the level of the ground is not always flat.
  All readings are taken from this point.
• Volume The amount of space, measured in cubic
  units, that an object or substance occupies.
• Pi / p A transcendental number, approximately
  3.14159, represented by the symbol p, that
  expresses the ratio of the circumference to the
  diameter of a circle and appears as a constant in
  many mathematical expressions
