Introduction to Engineering Graphics PDF First Year Notes

Engineering Graphics is an incredibly important study in the field of technology and engineering. Engineering Graphics is the branch of engineering which deals with how to draw technical objects before they can be built or engineered.

Some would say that Engineering Graphics is like the architecture of the construction industry. By this, we mean how construction workers construct the building, but it is designed by the architect. Similarly, machines and technological objects are built by engineers, and the design is laid out by the Engineering Graphic designers.

Engineering Graphics focuses on studying various components of design elements that extend to the study of engineering. Some of the concepts that the subject Engineering Graphics essentially studies are as follows:

  • Accurate freehand sketching
  • Plane surfaces
  • Plane figures
  • Solid figures
  • Surface development
  • Isometric and perspective projections
  • Various other concepts around solids and planes

Engineering Graphics Reference Books

Recognizing the importance of reference books in the life of a student is vital to so many proportions. With reference books, a student need not scour through an entire textbook, maybe sometimes even missing out on important points, because reference books have all the important points, important questions, important notes, etc. all in the midst of a few hundred pages.

The following is a list of some of the important Engineering Graphics reference books for the use of the student:

First-Year Engineering Graphics Curriculum

The First-Year Engineering Graphics curriculum consists of most of the basics for continuation of the course in Engineering Graphics. It is aimed at providing students with a strong base to continue the next few years of their studies in Engineering Graphics.

The following is Engineering Graphics curriculum for the first year. Please note that the pre-first unit for First-Year Engineering Graphics, which is Concepts and Conventions, is only there for the understanding of the student. It will not be tested for in the examination, but is only part of the curriculum to broaden the base of the engineering design student.
