QCAD and Libre CAD are examples of 2D CAD freeware. Different ‘levels’ of 2D CAD programs are available including free and open-source, which are simple, without the complications of scaling or placements. The programs include collections of models, curves, splines, and polylines. 2D – The 2D programs create ‘flat‘ drawings of structures with lines, circles, curves and so on.There’s been a lot of development in the CAD- human interface interaction from touchscreens to Virtual Reality/Augmented Reality. Designers are also using a computer mouse with CAD programs as well as a pen and digitizing graphics tablet. CAD is now available on cloud, web and mobile technologies, making it possible for the engineers to work with CAD on Mac, Windows PC or tablet.Retailers established that using Product Data Management and Product Lifecycle Management, they can successfully eliminate prolonged development time. The success demonstrated that the combination of CAD, PDM (Product Data Management) and the Internet could provide designers, architects, and engineers a seamless way of collaboration in a time-efficient way. The design of Ford Mondeo (Ford Motor Company) was created using Ford’s C3P (Computer-Aided Design, Computer-Aided Manufacturing, Computer-Aided Engineering, Blue print Washington DC, Product Data Management) platform. Ford’s announcement of the Ford Mondeo substantiated this in late 2000. Vendors showed interest in product data management (PDM) for reducing concept, design and manufacturing time. The 21 st century brought an era of sustainability in CAD software.The next decade saw the development of popular CAD design & drafting programs like Revit, Creo, SolidWorks and more. Autodesk succeeded in the 21st century with persistent updates made to AutoCAD product, comprising of tool palettes in 2003, functioning of the dynamic block in 2005 and support for Macs in 2011. Later on, Autodesk released AutoCAD 2000i, as the first web based CAD software application. Alibre released Alibre Design in 2000, the first 3D CAD software to accomplish client-server 3D modeling over the internet. The onset of the 21st century marked the release of CAD tools for clients.
