1. Sketching Practice “One picture is worth a thousand words.”

2. Pictorial Sketches #1 Shows the 3D perspective (height, width, and depth) in a 2D drawing width height 2D 3D depth

3. Horizon Line TOP SIDE FRONT Isometric Cube Width and depth lines are drawn at 30° from the horizon line. One view shows height, width, and depth. Width 30° Depth 30° Height 90°

4. Copy & Label this #2 (3 minutes) Height = 6 units

5. Isometric Thumbnail Sketch #3 (9 minutes) (9 minutes) Additive and Subtractive 3D sketch Follow the steps in your activity to complete this drawing on the isometric graph paper on page 6 6 units 3 units 2 units

6. Perspective #4 – pg6 Vanishing points are used to guide the lines in the object to the horizon line.

7. One-Point Perspective All lines in the depth project to one point (the vanishing point). #5 - Copy this one-point perspective sketch onto your activity. Label the front, top, and right side. (5 minutes) Vanishing Point (VP) 1st 2nd 3rd

8. Two-Point Perspective In two-point perspective, the width lines converge on one vanishing point (VP1), and the depth lines converge on the other vanishing point (VP2). #6-Copy this two-point perspective onto your activity sheet. Label the top, front, and side. (5 minutes) VP1 VP2

9. Orthographic (Multiview Drawings)

10. Orthographic Projection

11. Orthographic (Multiview) Sketching #7 An orthographic sketch is used to show true scale and shape. Notice the top view is directly above the front with the right side view directly to the right of the front.

12. Orthographic (Multiview) Sketching #8 Copy this orthographic sketch onto your activity sheet. Label the top, front, and right side. Don’t forget the hidden lines. (7 minutes) 8 squares 9 squares 6 squares Red lines are construction lines …. optional
