That is the art of civil CAD. It’s infrastructure’s best-kept secret. And it’s beautifully, mathematically, wetly complicated.

Historically, civil engineering designs were drafted by hand with pencil and paper. While CAD technology emerged in the late 1950s, it took until the late 1980s for computer performance to make digital drafting common in professional firms [7]. Today, the industry has shifted from simple 2D shapes to , where designed objects are "intelligent"—a road isn't just a set of lines, but a data-rich model containing alignments, cross-sections, and earthwork calculations [3].
