Sketching Practice

“One picture is worth a thousand words.”

Pictorial Sketches #1

• Shows the 3D perspective (height, width, and depth) in a 2D drawing

Isometric Cube• Width and

depth lines are drawn at 30° from the horizon line.

• One view shows height, width, and depth.

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.

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)

Orthographic (Multiview Drawings)

Orthographic Projection

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.
