Subject Code: EME1036
Aim of Subject: To provide the students with the elements of descriptive geometry and machine drawing.
Learning Outcome of Subject: At the completion of the subject, students should be able to :
  • Use conventional drawing tools to draw basic engineering geometry.
  • Distinguish the difference between First Angle Projection and Third Angle Projection, and apply standard line practices to multi-view drawings.
  • Explain the difference between an isometric projection and an isometric drawing, and create an isometric drawing.
  • Apply the theory of oblique projection to create oblique drawings.
  • Draw primary, secondary, and tertiary auxiliary views using reference planes and fold lines, and construct true length lines using auxiliary view and revolution method.
  • Define and apply the principles of geometric intersections.
  • Identify, define and create the developments of various solids and transition pieces.
  • Apply the concept of cutting planes to create section views and represent section views using conventional practices.
  • Differentiate machine and assembly drawings.
  • Use of conventional symbols for fasteners.
