Engineering Drawing Flashcards
The graphical representation of any object or idea. It can be prepared either using free hand or using engineering instruments or using computer program.
Drawing
2 Types of Drawing
- Artistic Drawing
- Engineering Drawing
The drawing representing any object or idea which is sketched in free hand using imagination of artist and in which proper scaling and dimensioning is not maintained.
Artistic Drawing
A graphical language used by engineers and other technical personnel associated with the engineering profession which fully and clearly defines the requirements for engineered items.
Engineering Drawing
It is a two-dimensional representation of a three-dimensional object.
Engineering Drawing
An engineering drawing provides al information about:
- Size
- Shape
- Surface type
- materials etc. of the object
Application of Engineering Drawing
- It is used in ships for navigation.
- For manufacturing of machines, automobiles, etc.
- For the construction of buildings, roads, bridges, dams, electrical and telecommunication structures etc.
- For manufacturing of electric appliances like TV, phone, computers, and etc.
4 Types of Technical Drawing in the Field of Engineering
- Geometrical Drawing
- Mechanical Engineering Drawing
- Civil Engineering Drawing
- Electrical & Electronics Engineering Drawing etc.
The art of representing geometric objects such as rectangles, squares, cubes, cones, cylinders, spheres etc. on paper
Geometric Drawing
If the object has only 2 dimension i.e. length and breadth (as rectangles, squares, triangles, etc.)
Plane Geometrical Drawing
If it has 3 dimension i.e. length, breadth, and thickness/depth (as cube, prism, sphere, cylinder, etc.)
Solid Geometrical Drawing
It shows the position of different objects and elements of the structure in a two-dimensional view. Only the length and width of objects are shown here.
Plan
It shows a view along the height of the structure. Elevation can be presented in 2D or 3D. In the 2D elevation view, either height and length or height and width are show.
Elevation and Section
It shows the detailed requirement of reinforcement and their arrangement in structure. It also shows the specification and properties of construction materials like concrete, steel, timber etc.
