CBSE Class 12 Engineering Graphics Syllabus for Isometric Projection of Solids

  1. Construction ofisometric scale showing main divisions of 10mm and smaller divisions of1mm, also showing theleading angles. Drawing helping view/s such as triangles, pentagon, hexagon, etc.,usingisometric scale.
  2. Isometric projections (drawn toisometric scale) of sol ds such as cube, regular prism and pyramids (triangular, square, pentagonal and hexagonal), cone, cylinder, sphere, hemi· sphere, frustum of right regular pyramids (triangular, square, pentagonal, hexagonal) and cone, when they are cut by a plane parallel to the base. The axis and the base side of the solid should be either perpendicular to HP I VP or parallel to HP and VP. (Indicate the direction of viewing)
  3. Combinat on of two solids (except "frustum" of Pyramids and Cone) Keeping the base side parallel or perpendicular to HP/VP and placed centrally together, axis of both the solids should not be given parallel to HP.
