Introduction
Mechanical CAD (Computer-Aided Design) has become one of the most important technologies in modern engineering and manufacturing. From automotive components to industrial machinery, Mechanical CAD software helps engineers create accurate, efficient, and production-ready designs.
In recent years, Mechanical CAD has evolved rapidly with the integration of Artificial Intelligence (AI), cloud technology, automation, simulation tools, and smart manufacturing systems. Today’s CAD platforms are no longer limited to basic drafting and modeling — they are becoming intelligent engineering ecosystems.
What is Mechanical CAD?
