And it is the only practical way of making sense of the ensuing deluge of data.The changes wrought by computers in biology resemble those in the aircraft and car industries a decade or so ago, after the arrival of powerful software for CAD (computer-aided design) and CFD (computational fluid dynamics).
But he is also a cad and a narcissist.His presence on the campaign trail reminded voters that Mrs Clinton is hardly a self-made woman she rose to power on his coat-tails and endured repeated humiliations in the process.
For the most part, this is still carried out with old-fashioned two-dimensional elevation and plan drawings, created by hand or using computer-aided design (CAD) software.
That could slow the mainstream adoption of 3D printing and imply that anyone uploading CAD files to a public site was somehow infringing on rights, notes Cory Doctorow, a Canadian science writer who blogs for Boing Boing.
This integrated process is commonly called CAD/CAM.
CAD/CAM systems also allow design data to be stored in numerical (digitized) form, from which machine-control tapes and disks may be prepared directly.
In a sense, CAD/CAM allows the mass production system to manufacture customized "handmade" articles.
CAD/CAM involves not only the automation of the manufacturing operations but also the automation of elements in the entire design-and-manufacturing procedure.
In an ideal CIM system, computer technology is applied to all the operational and information-processing functions of the company, from customer orders through design and production (CAD/CAM) to product shipment and customer service.
