Back in time, the construction of architectural masterpieces such as Notre Dame Cathedral spanned over centuries and required hundreds of drafts and tons of effort. With CAD (Computer-aided design) tools, architects and engineers nowadays can automate manual drafting and documentation and visualize their ideas in 2D and 3D space. CAD involves analyzing objects from different angles, adjusting their parameters, and testing them by simulating real-world conditions.^[1]

CAD is widely popular in automotive, shipbuilding, aerospace industries, industrial and architectural design, prosthetics, not to mention computer design, and digital content creation.
