Planning Complex Models

The Decomposition Process

• Identify the overall form

• List the components

• Define relationships

• Plan the order

Example: A Chair

Components

• Seat (flat box)
• Backrest (flat box, angled)
• Four legs (cylinders/boxes)
• Optional: Arm rests

Relationships

• Legs at corners of seat
• Backrest at back edge of seat
• Arm rests connect legs to backrest

Build Order

• Seat (primary reference)
• Legs (positioned relative to seat)
• Backrest (attached to seat back)
• Arms (connect everything)

Iteration

Professional workflow:

• Rough block-out - Basic shapes, test proportions
• Refine - Adjust dimensions
• Detail - Add smaller features
• Polish - Materials, final touches

Don't perfect things too early!
