  1. 1. 121 1208 Engineering Drawing I Carry Prameswari Program Studi Teknik Penerbangan Fakultas Teknologi Kedirgantaraan Universitas Dirgantara Marsekal Suryadarma
  2. 2. Topics • Creating orthographic projection • Auxiliary view
  3. 3. Creating an Orthographic Projection • Choose a front view. – Which view shows the most about the object? C
  4. 4. Creating an Orthographic Projection • Decide how many views are needed. – How many and which views? 2 Front Top For procedural reasons, we will continue this example by drawing all 3 standard views.
  5. 5. Creating an Orthographic Projection • Draw the visible features of the front view.
  6. 6. Creating an Orthographic Projection • Draw projectors off of the front view.
  7. 7. Creating an Orthographic Projection • Draw the top view.
  8. 8. Creating an Orthographic Projection • Project back to the front view.
  9. 9. Creating an Orthographic Projection • Draw a 45 projector off the front view.
  10. 10. Creating an Orthographic Projection • Draw projectors over to the 45 line and down.
  11. 11. Creating an Orthographic Projection • Draw the right side view.
  12. 12. Creating an Orthographic Projection • Project back if needed.
  13. 13. Creating an Orthographic Projection • Draw centerlines where necessary.
  14. 14. Creating an Orthographic Projection
  15. 15. Completed Drawing
  16. 16. Exercise
  17. 17. Draw three views of the following components in first angle projection. Show hidden detail when necessary. Use A4 paper, and give drawing title on each drawing. All dimensions are in (mm).
  18. 18. Auxiliary View An auxiliary view is an orthographic view taken in such a manner that the lines of sight are not parallel to the principal projection planes (frontal, horizontal, or profile). There are an infinite number of possible auxiliary views of any given object.
