Before you write — three drafting tips
- A row of road pieces on its own folds like a chain: brace it with triangles below or above the deck.
- Squeezed beams buckle when they are long - split them or use steel or carbon there.
- Cables only pull. Tie a lift platform with a pinned truss, not with stays from a fixed pylon.
