ENGINEERING DRAWING

TECHNICAL DRAWING

a precise diagram that communicates design information for all object

COMMUNICATION

They bridge the gap between the designer and the person

INSTRUCTION

provide all necessary information for manufacturing

INSPECTION

Defines the geometric requirements for inspecting

ASSEMBLY

how individual components fit together to form a complete system

VIEWS

multiple views of the objectare used to provide a complete understanding to it's 3D form

TOP VIEW

FRONT VIEW

SIDE VIEW

DIFFERENT KINDS OF VIEW

DIMENSIONS

precise measurements that define the size and location of the object

NOTES

written text that provides specific instructions or information

SYMBOL

Standard graphics, use to represent specific engineering features material

TITLE BLOCK

standard section, usually in bottom right containing critical information

SKETCHING

‎mean free hand drawing

SECTION LINES

‎often at 45°, used to show the cut surfaces of an object in section views

ORTHOGRAPHIC PROJECTION

‎uses multiple 2D views to show an object shape and size

‎DRAWING

‎using drawing instruments

‎

‎ISOMETRIC PROJECTION

‎provides a single 3D view by showing three sides of an object

‎

‎LINE STYLE

‎

‎it makes drawing easiest to read

‎LINE

‎geometric,that has no thickness

RAY

straight lines that extend into infinity

LINE STYLE CONVENTIONS

‎use of different line style and widths is important in technical drawing

CUTTING PLANE LINE

‎also known as line of section or trace of cutting plane

REDUCTION SCALE

‎THe drawing is half to the actual object( a scale 1:2 in Engineering Drawing means)

‎

ENGINEERING LETTERING

it was introduced by GUTENBERG

‎

15th century

lettering was introduced by this year

GOTHIC

‎plainest and mist legible style

AMERICAN NATIONAL STANDARDS INSTITUTE

‎they suggested a standardization of the technical writing made by REINHARDT

GUIDELINES

‎ensures uniformity in height

UNIFORMITY

‎essential in any lettering styles

THICK DASHES

‎ is a line type used in technical drawing and engineering to represent features that are not visible (HIDDEN LINES) in the current view.

THICK CONTINUOUS

‎ is the standardized line type used to represent the visible edges and outlines (VISIBLE LINES) of an object,used in each view.

THIN CHAIN

‎used to indicate the center or axis of circular, cylindrical, or symmetrical objects.

THIN CONTINUOUS

‎Used to dimensioning lines

ISOMETRIC DRAWING

‎ a type of technical or engineering drawing that visually represents a three-dimensional object in two dimensions. (method)
