Isometric Drawing
• “isos” = equal• “metron” = measure• All 3-D measurements are scaled equally• Use isometric dot paper to show three
sides of a figure from a corner view
Example 1• Make an isometric drawing
of the cube structure on page 10 of your book.
Orthographic Drawing
• Shows a top view, a front view, and a right-side view
• Like a blueprint of a building
Example 2• Make an orthographic drawing of the
figure on page 11 of your book.
Foundation Drawing
• Shows the base of a structure and the height of each part
• Used for skyscrapers!
Example 3• Make a foundation drawing for the isometric
drawing on page 11 of your book.
Nets
• Two-dimensional pattern that you can fold to form a three-dimensional figure
• Shows all of the surfaces of a figure in one view
Example 4
• What figure will this net make?
Example 5
• Draw a net for the graham cracker box.
Homework
• P. 13-15
• 1-16 all (with work)• 23-26• 28-30
