  1. 6.1: Solid Shapes Expectation: G2.2.1: Identify or sketch a possible three-dimensional figure, given two-dimensional views (e.g., nets, multiple views). Create a two-dimensional representation of a three-dimensional figure. 6.1: Solid Shapes

  2. Isometric Drawing • An isometric drawing is a drawing in which the horizontal lines of the object are drawn at 30° angles to the horizontal. This gives us the appearance of 3 dimensions. 6.1: Solid Shapes

  3. Isometric Drawing 30º 30º 6.1: Solid Shapes

  4. Draw a cube on isometric dot paper. 6.1: Solid Shapes

  5. For edges that exist but cannot be seen, we draw dashed lines. These dashed lines are called hidden lines. 6.1: Solid Shapes

  6. Make an isometric drawing of a stack of cubes that is 3 cubes tall. 6.1: Solid Shapes

  7. Complete Activity #1 on page 373 (first 2 drawings in #1 & 2). Complete Activity #2 on pages 373. 6.1: Solid Shapes

  8. Orthographic Projections • Orthographic projections are views of an object in a direction perpendicular to the plane of the object. 6.1: Solid Shapes

  9. Orthographic Views • There are 6 basic orthographic projection views: • front, back, top, bottom, right and left side views 6.1: Solid Shapes

  10. Draw the six basic orthographic projection views of the figure below. 6.1: Solid Shapes

  11. Draw the six basic orthographic projection views of the figure below. 6.1: Solid Shapes

  12. Draw the 6 orthographic projection views of the figure below. What are the volume and surface area of the figure? 6.1: Solid Shapes

  13. Assignment • pages 375-377, • # 12-16 (evens), 21-26 (all), 28, • 31-34, 38-43 (except 41) 6.1: Solid Shapes
