The document discusses different types of technical drawings used in architecture. A floor plan is a horizontal section view from above showing the arrangement of spaces and features at a particular level of a building. An elevation is a flat view of one facade of a building, typically labeled with the compass direction it faces. A cross section, or section, represents a vertical plane cut through an object, showing anything cut by the section plane with a solid fill. Isometric and axonometric projections are a way of representing a 3D object in a scaled drawing to show the relationship between multiple sides. Perspective drawings represent an approximate view from a fixed viewpoint. Sketches and diagrams are quick, freehand drawings used to develop and communicate design ideas.

5. A floor plan is the most fundamental architectural diagram, a view from
above showing the arrangement of spaces in, showing the arrangement
at a particular level of a building.
Technically it is a horizontal section cut through a building
(conventionally at four feet / 1200mm/1.2 m above floor level), showing
walls, windows and door openings and other features at that level. The
plan view includes anything that could be seen below that level: the
floor, stairs (but only up to the plan level), fittings and sometimes
furniture.

8. An elevation is a view of a building seen from one side, a flat
representation of one facade. This is the most common view used to
describe the external appearance of a building. Each elevation is labelled
in relation to the compass direction it faces, e.g. the north elevation of a
building is the side that most closely faces north

17. A cross section, also simply called a section, represents a vertical plane cut
through the object, in the same way as a floor plan is a horizontal section
viewed from the top. In the section view, everything cut by the section
plane is shown as a bold line, often with a solid fill to show objects that
are cut through, and anything seen beyond generally shown in a thinner
line

21. Isometric (30 deg) and axonometric (45 deg) projections are a
simple way of representing a three dimensional object,
keeping the elements to scale and showing the relationship
between several sides of the same object, so that the
complexities of a shape can be clearly understood

26. Perspective in drawing is an approximate representation on a
flat surface of an image as it is perceived by the eye.
Perspective is the view from a particular fixed viewpoint

30. A sketch is a rapidly executed freehand drawing, a quick way to record
and develop an idea, not intended as a finished work. A diagram may
also be drawn freehand but deals with symbols, to develop the logic
of a design. Both may be worked up into a more presentable form
and used to communicate the principles of a design
