The release of AutoCAD marked a significant milestone, offering a more accessible and affordable CAD solution that could run on personal computers. This democratization of CAD technology allowed smaller educational institutions to incorporate design software into their programs. Throughout the 1980s and 1990s, improvements in computing power and software capabilities led to the development of more sophisticated CAD systems. Parametric modeling emerged with software like Pro/ENGINEER, developed by PTC in 1987, which introduced a new way of designing that relied on mathematical relationships between elements. The transition from 2D drafting to 3D modeling represented another critical evolution. Software like SolidWorks, launched in 1995 by Jon Hirschtick and his team, made 3D modeling more intuitive and accessible to students. SolidWorks' user-friendly interface and powerful features quickly gained popularity in educational institutions. Meanwhile, Dassault Systèmes continued to advance their flagship product, CATIA, initially developed for the aerospace industry but later adapted for educational purposes. As the internet became more prevalent, CAD software began to incorporate online functionalities. Cloud-based solutions emerged, exemplified by platforms like Onshape, founded in 2012 by a team led by former SolidWorks CEO John McEleney. Onshape's fully cloud-based CAD system allowed for real-time collaboration and eliminated the need for costly hardware, making it especially appealing for educational use. Throughout these transitions, software companies and educators have worked closely to ensure that CAD tools evolve to meet the changing needs of students and the demands of an increasingly digital world.
