Rapid concept development: Envisioned designs can be accurately sketched for early visualization and 3D printed rapid prototypes. The benefits of CAD integration across the product development process are: Generative design makes the computer a co-creator using artificial intelligence to suggest optimal shapes to meet specific mechanical problems.
Advanced simulations allow testing of a design according to numerous mechanical aspects and take only hours instead of days. The most recent CAD software systems are cloud-based, enabling developers to collaborate on the same model through different workstations and delegate intensive algorithms such as generative design, simulation, and rendering to the cloud. In addition, new features and modules were developed for a variety of CAD programs that allowed designers to not only develop the physical product, but also render, animate, and simulate it, as well as integrate product development into the overarching processes of project management and product lifecycle management (PLM). The 2000s marked an emergence of open-source CAD systems such as FreeCAD. This was adopted by the now well-known systems SolidWorks (1995), SolidEdge (1996), and Autodesk Inventor (1999). In the 1990s, solid modeling engines were enhanced with boundary representation, a more consistent way to describe virtual objects by their boundaries and interconnections. CAD software tools empower designers to explore design ideas, modify designs easily, visualize concepts through renderings, simulate how a design performs in the real world, draft documentation, share designs for feedback, and more-facilitating innovation and allowing companies to get to market faster.ĬAD software has been around since 1959, when Doug Ross, a researcher at MIT, coined the term ‘computer-aided design’ after developing a program that allowed his team to draw electronic circuit drawings on a computer, thereby realizing its potential for rapid modification and exploration.īy the early 1980s, CAD had become integrated into the workflow of the automotive, aviation, and consumer electronics manufacturers that could afford it. Computer-aided design (CAD) is a method to digitally create 2D drawings and 3D models that has replaced manual drafting across a wide range of industries.
