  1. Graphic Science (MEL110) (2-0-4) Dr. Ashish K Darpe, Department of Mechanical Engineering   III-176 #6095(O), #1618(R) Course for Part 1: Introduction, general instructions for lettering, instruments, etc. Projection Systems- perspective, orthographic, isometric & oblique, Dimensioning Practicals for Part 1 – sketching on tracing sheets. Tracing sheet pad, one graph paper, H&HB pencils, eraser, zero grade sand paper.

  2. Text Book:Fundamentals of Engineering Drawing Luzadder & Duff (9th or 11th Edition) Prentice-Hall of India Additional Reference Book: Engineering Drawing, N D Bhatt Some practicals on computer in Computer Aided Graphics Instruction Laboratory (CAGIL) Room No. III-331-332

  3. COURSE OVERVIEW Lettering Projections Orthographic Axonometric Isometric Oblique Plane geometric constructions (Engg.Curves) Projections on Auxiliary Planes Projection of planes and solids  Sectional Views   Intersection of surfaces  Development of surfaces  Computer Aided Drawing

  4. ORTHOGRAPHIC PROJECTIONS ISOMETRIC PROJECTIONS

  5. ENGINEERING CURVES

  6. AUXILIARY VIEWS

  7. INTERPENETRATION OF SURFACES

  8. DEVELOPMENT OF SURFACES

  9. SECTION OF SOLIDS

  10. ORTHOGRAPHIC PROJECTION A) HP IS ROTATED 900 DOUNWARD B) PP, 900 IN RIGHT SIDE DIRECTION. THIS WAY BOTH PLANES ARE BROUGHT IN THE SAME PLANE CONTAINING FP. PP FP Y X HP ACTUAL PATTERN OF PLANES & VIEWS OF ORTHOGRAPHIC PROJECTIONS DRAWN IN FIRST ANGLE METHOD OF PROJECTIONS Frontal Plane (Vertical Plane) PP PATTERN OF PLANES & VIEWS (First Angle Method) FP Y X Horizontal Plane (Top Plane) HP FV LSV X Y TV PP IS ROTATED IN RIGHT SIDE 900 AND BROUGHT IN THE PLANE OF FP. HP IS ROTATED DOWNWARD 900 AND BROUGHT IN THE PLANE OF FP.

  11. FOR T.V. FOR S.V. FOR F.V. THIRD ANGLE PROJECTION IN THIS METHOD, THE OBJECT IS ASSUMED TO BE SITUATED IN THIRD QUADRANT ( BELOW HP & BEHIND OF FP. ) PLANES BEING TRANSPERENT AND INBETWEEN OBSERVER & OBJECT. P.P. F.P.
