Beginning with early sketchpad systems in the 1960s like Sutherland's Sketchpad, it highlights the development of foundational geometric modeling techniques and the emergence of companies like Dassault Systèmes (CATIA) and SDRC (IDEAS). The post then follows CAD's progression through the rise of parametric and solid modeling in the 1980s and 90s, facilitated by companies like Autodesk (AutoCAD) and PTC (Pro/ENGINEER). Finally, it touches on more recent advancements like direct modeling, cloud-based CAD, and the increasing accessibility of CAD software, culminating in modern tools like Shapr3D.

  A comprehensive exploration into the genesis and evolution of Computer-Aided Design (CAD) is presented in David Weisberg's blog post titled "History of CAD." The narrative meticulously traces the journey of this transformative technology, starting from its nascent stages in the 1950s and 60s. Weisberg highlights the pioneering work of Dr. Patrick J. Hanratty, often recognized as the "father of CAD," and his development of PRONTO, widely considered the first commercial numerical control programming system. This groundbreaking software, initially deployed for machining aircraft parts, laid the groundwork for future CAD systems.

  The post elaborates on the subsequent emergence of SKETCHPAD, a revolutionary system conceived by Ivan Sutherland at MIT. This innovation introduced interactive computer graphics and the concept of hierarchical design, fundamentally altering the approach to design and drafting. The blog post meticulously details how SKETCHPAD's ability to manipulate graphical elements with a light pen foreshadowed the intuitive interfaces of modern CAD software.

  Moving beyond these early milestones, the narrative delves into the burgeoning commercialization of CAD during the 1970s. The introduction of turnkey CAD systems, packaged with dedicated hardware and software, marked a significant shift in accessibility. Companies like Applicon, Computervision, and Intergraph played pivotal roles in this era, making CAD technology increasingly available to a wider range of industries. The post underscores the impact of these systems on automotive and aerospace design, revolutionizing product development processes.

  The evolution of CAD continued through the 1980s and 90s, with the rise of personal computers democratizing access to this once-exclusive technology. AutoCAD, developed by Autodesk, emerged as a dominant force, enabling engineers and designers to leverage the power of CAD on readily available hardware. The blog post emphasizes the significance of this transition, fostering a wider adoption of CAD across various disciplines.

  Weisberg's account extends to encompass the transformative influence of parametric and solid modeling, which further enhanced the capabilities of CAD systems. These advancements facilitated the creation of more complex and detailed 3D models, empowering designers with greater control and precision. The narrative also touches upon the emergence of Computer-Aided Manufacturing (CAM) and its seamless integration with CAD, streamlining the transition from design to fabrication.

  Finally, the post concludes with a glimpse into the future of CAD, highlighting the growing prominence of cloud-based CAD and the potential of emerging technologies like virtual and augmented reality. The ongoing integration of artificial intelligence and machine learning promises to further revolutionize CAD, paving the way for more intelligent and automated design processes. Weisberg’s insightful exploration offers a comprehensive understanding of CAD's rich history and its continuing evolution, underscoring its profound impact on various industries and the world of design.
