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

- 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.

- Draw a cube on isometric dot paper.

6.1: Solid Shapes

- For edges that exist but cannot be seen, we draw dashed lines. These dashed lines are called hidden lines.

6.1: Solid Shapes

- Make an isometric drawing of a stack of cubes that is 3 cubes tall.

- Orthographic projections are views of an object in a direction perpendicular to the plane of the object.

6.1: Solid Shapes

- There are 6 basic orthographic projection views:
- front, back, top, bottom, right and left side views
