Engineering Drawing / Drafting

Drawing means lines, shapes, finishes, sizes and colour combined to construct objects or structures. It will be a cumbersome task narrating an idea without drawing if the idea is an object or structure. Engineering is heavily depending drawings, since has developed a global language named Engineering Drawing, capable to express its objects and structure to everyone without the barrier of human languages. Drawings conveniently helps to explain and record an idea that can be smoothly conveyed to one person to other or sometimes to machine too.

What is Drawing?

Drawing is a kind of visual language that can read, record and express objects, structures, events, feelings through eyes. It always depends visual medium like paper, surfaces, electronic screens and so on. Drawings created for events and feelings categorized under art form that will be done by specially talented people called Drawing artists. Drawings of objects and structures are categorized under engineering that to build, manufacture, control, and transport to be learned and created by anyone who practice it.

What is Drafting?

The process of creation, modification, development and editing of drawing is called drafting. Drafting gives output in a medium generally a sheet of paper or on a screen. Since it is a process, it needs well developed procedure for quality output. There are mainly two types of drafting - Manual drafting and Computerized drafting - both needs skills to achieve quality output.

As we see Drawing itself is a language, it conveys ideas and feelings to one person to another as to what other human language do. Hence Engineering Drawing conveys engineering ideas, objects and structures to other person to develop, edit, modify, construct and finishes. Engineering drawing has well developed procedures, rules, and norms that universally accepted and implemented for intended output. The procedural process for creating, developing, editing, modifying Engineering Drawing is called Engineering Drafting. It can be done by freehand or manually with the help of sophisticated hand tools or with the help of computerized software.

Phases of Engineering Drawing

How big or complex your idea, it can be drawn by making small pieces of hand sketches. Then it can be joined, developed upto its size and complexity. Some of the main phases are:

  • Hand sketches
  • Joining and development of hand sketches
  • Dimensions, materials, technology to hand sketches
  • Scaled drawing using tools or computer
  • Developing views in 2D platform


  • Conversion from 2D to 3D
  • 3D Rendering, lighting and rotations
  • Animation
