1. Old photographic copies of hand-drawn engineering designs featuring white lines on blue paper.
2. The revolutionary 1982 software that brought digital design to affordable, everyday desktop personal computers.
3. A digital 3D skeleton or grid layout made of thousands of tiny triangles and squares.
4. The world's very first interactive computer design program created in 1963.
6. The exhausting historical process of drawing precise technical plans entirely by hand on large boards.
7. Testing a vehicle or machine model on a computer screen under simulated real-world conditions instead of exploding a physical prototype.
