Benefits of Sketching
Imagine a variety of ideas
Explore Alternatives
Foster Better Discussions: Allows people to agree on what they see, not what they imagine; Saves time to replace words to explain a situation
Helps to remember: Breaks things down in components; Notice parts of the product
Types of Perspective Drawings
One-point Perspective
Step 1: Draw a line across the middle of your page - this will be my horizon
Step 2: In the centre put a small dot or cross to show the vanishing point
Step 3: Draw the front view of a cube
Step 4: From each corner take a light line to the vanishing point
Step 5: Decide on the depth of your cube then draw horizontal and vertical parallel lines
Step 6: Add thick and thin lines and erase your unwanted construction lines
Two-Point Perspective
Step 1: Draw a line across the middle of your page - this will be the horizon
Step 2: Draw two vanishing points on the line
Step 3: Draw one side of your cube - using projection lines to one vanishing point
Step 4: Draw in the other side - once again using projection lines
Step 5: Draw two projection lines to the vanishings point for the base - draw in the outlines
Step 6: Add thick and thin lines and erase your unwanted construction lines
