Creating a free-standing plastic structure containing over ten thousand bricks introduces brutal physical constraints. Plastic softens under sustained room temperatures. Cantilevered sections sag. Baseplates twist under uneven load distribution. When designing the Eiffel Tower, the Billund engineering crew broke the model down into four distinct vertical modules connected by interlocking crossbeams, allowing the structure to distribute its weight downward through arched corner pillars.
The Titanic required an entirely different mechanical solution. To prevent its 53-inch hull from snapping in half when lifted, internal Technic girders run along the ship's keel. The vessel separates into three modular segments linked by heavy-duty pin connections, giving builders an intimate look at interior cross-sections, including boiler rooms, smoking lounges, and reciprocating steam engines, without sacrificing long-term lateral stability.
