Before AutoCAD: When Architecture Was Drawn by Hand
Long before AutoCAD and digital modeling transformed architectural practice, every project was created by hand. Architects and draftspeople worked with pencils, technical pens, rulers, triangles, compasses, scales, and large sheets of paper to develop plans, elevations, sections, and detailed drawings.
Large-scale projects often required enormous drawings laid out across tables or even directly on the floor. Every line had to be carefully measured and drawn, and even a small mistake could mean hours of corrections or, sometimes, starting a drawing again.
Architectural ideas were developed through sketches, physical models, tracing paper, and countless revisions. Drawings were copied manually, dimensions were calculated by hand, and changes had to be incorporated directly into the original documents.
The arrival of computer-aided design, especially CAD software such as AutoCAD, dramatically changed this process. Digital tools made it possible to edit, duplicate, measure, and reproduce drawings with unprecedented speed and precision.
Yet hand-drawn architecture represented more than a technical process. It was a deeply physical and visual way of thinking—where every line was part of the architect's process of imagining and shaping space.
