Is architecture best represented in code? It's all about patterns.

Why do we have CAD tools at all when architects and engineers could just be writing code for buildings?

Some people need those visual metaphors in order to create something. There are people who think differently (from you) and a CAD tool would simply be a hindrance. And if the resulting building is top quality why care how the blueprints were made?
