Architecture Before CAD and BIM 🎨🤖

Before computers took over the drawing board, architecture was crafted entirely by hand.

Architects and engineers worked with pencils, compasses, erasers, and T-squares—on large sheets of paper spread across drafting tables. It wasn’t just a job for one person; entire rooms, even warehouses, were filled with drafters carefully tracing every detail by hand.

Every change meant redrawing everything from scratch. Precision was essential—and time-consuming.

This analog method dates back thousands of years. The earliest known engineering drawing comes from 2000 B.C.: a plan of a Babylonian castle carved in stone.

The shift began in 1963, when Ivan Sutherland created Sketchpad, the first graphical CAD program. But it wasn’t until the 1980s and 90s—thanks to companies like Autodesk—that CAD became widely adopted.

CAD changed how we draw. Now BIM is changing how we think and interact with construction and the overall processes of a project. Today, with the rise of AI, we’re witnessing another leap—one where the creative process is being reimagined once again.

But it all started with pencil on paper. And a lot of patience.
