: 2D blueprints moved into 3D space, allowing for simulations and stress tests before a single chip of metal is cut.
The biggest "plot twist" in this story was the move from simple plus/minus tolerances to . Engineering Drawing for Manufacture (Manufactur...
: In the late 18th century, Gaspard Monge developed Descriptive Geometry . This allowed 3D objects to be represented accurately on 2D paper using orthographic projection. : 2D blueprints moved into 3D space, allowing
: Traditional coordinates created "square" tolerance zones that often rejected perfectly functional parts. This allowed 3D objects to be represented accurately
: Exactly what the shape, size, and material must be.
Today, an Engineering Drawing for Manufacture is the final checkpoint of the design process. It captures: : The physical form.
Without this "story" and its strict rules, modern aviation, medicine, and technology would literally fall apart.
