Student ExpectationsSlide3
There are many ways to represent a three dimensional object. An
orthographic drawing
shows six different views of an object: top, bottom, front, back, left side, and right side.Slide4
Example 1: Drawing Orthographic Views of an Object
Draw all six orthographic views of the given object. Assume there are no hidden cubes.Slide5
Example 1 Continued
Draw all six orthographic views of the given object. Assume there are no hidden cubes.

Isometric drawing
is a way to show three sides ofa figure from a corner view. You can use isometric dot paper to make an isometric drawing. This paper has diagonal rows of dots that are equally spaced in arepeating triangular pattern.Slide11
Example 2: Drawing an Isometric View of an Object
Draw an isometric view of the given object. Assume there are no hidden cubes.Slide12

Example 2
Draw an isometric view of the given object. Assume there are no hidden cubes.Slide13
Example 4A: Relating Different Representations of an Object
Determine whether the drawing represents the given object. Assume there are no hidden cubes.
No; the base has one cube too many. Slide14
Example 4B: Relating Different Representations of an Object
Determine whether the drawing represents the given object. Assume there are no hidden cubes.
Yes; the drawing is a two-point perspective view of the object. Slide15
Example 4C: Relating Different Representations of an Object
Determine whether the drawing represents the given object. Assume there are no hidden cubes.
Yes; the drawing is an isometric view of the object. Slide16
Example 4D: Relating Different Representations of an Object
Determine whether the drawing represents the given object. Assume there are no hidden cubes.
Yes; the drawing
shows the six orthographic views of the object. Slide17
