CAD-Architectural-Drawing Definitions
Computer-aided design (CAD) is a contemporary tool to draft architectural designs and spaces. CAD allows the architect to draft and edit drawings faster and more easily than traditional drafting. There are six different drawing types used by the architect: plan, section, elevation, isometric, perspective and diagrams.

-
Plan
-
Plans are architectural CAD drawings that show a horizontal cut through a structure, exposing a building's organization of rooms and spaces.
Section
-
Sections are architectural CAD drawings showing vertical cuts through a structure. They are used to depict floor and building heights as well as vertical connectivity.
-
Elevation
-
Elevations are architectural CAD drawings that show a wall's face, expressing where every element is placed vertically on a facade or interior.
Isometric
-
Isometric drawings are architectural CAD drawings that represent the three-dimensionality of a structure or space. Every line's length in an isometric drawing is represented accurately to scale, but the angles of material connection in an isometric drawing are not correct. Many popular video games use isometric projection to show spaces; this is the same method for an isometric drawing.
Perspective
-
Perspectives are architectural CAD drawings that depict what the eye or a camera sees. The drawings are not to scale, but they accurately represent how a structure or space is perceived.
Diagrams
-
Diagrams are architectural CAD drawings that express structural data visually. A structural diagram, showing the amount of load or weight a beam must carry, is an example of an architectural CAD diagram.
