AutoCAD

AutoCAD is the foundational computer-aided drafting software, setting the standard for 2D precision drawing and documentation for decades. While it includes robust 3D tools, its core strength remains in creating detailed architectural plans, engineering schematics, and construction documents. Its extensive library of industry-specific toolsets (Architecture, Electrical, Map 3D) and powerful customization via LISP and APIs make it indispensable in AEC, manufacturing, and civil engineering. A subscription-based product from Autodesk, its unparalleled legacy, precision, and specialized vertical solutions secure its high rank for professional drafting and documentation workflows.
