Subject Code: EME1126
Aim of Subject: To provide students with the elements of descriptive geometry
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
