Sketching Practice
“One picture is worth a thousand words.”
Pictorial Sketches #1
• Shows the 3D perspective (height, width, and depth) in a 2D drawing
width

Horizon Line
TOP
SIDEFRONT
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° H

Copy & Label this #2

Isometric Thumbnail Sketch #3(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

Perspective #4 – pg6
• Vanishing points are used to guide the lines in the object to the horizon line.
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
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
Orthographic (Multiview Drawings)
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.
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)
