CAD standards product shape data" is under development. It defines how to represent quality criteria together with measurement requirements and representation of inspection results. CAD standards CAD Standards are a set of guidelines for the way Computer-aided drafting (CAD), or (CADD) Computer Aided Design and Drawing, drawings should appear, to improve productivity and interchange of CAD documents between different offices and CAD programs, especially in architecture and engineering. Most common: Samples of standardised layers: Thickness for pens and plot: "0,13 mm Gray, 0,18 mm Red, 0,25 mm White, 0,35 mm Yellow, 0,50 mm Magenta, 0,70 mm Blue, 1,00 mm Green". In AutoCAD
Computer-assisted surgery surgical intervention will be planned and simulated virtually, before actual surgery takes place (computer-aided surgical simulation [CASS]). Using dedicated software, the surgical robot will be programmed to carry out the planned actions during the actual surgical intervention. In computer-assisted surgery, the actual intervention is defined as surgical navigation. Using the surgical navigation system the surgeon uses special instruments, which are tracked by the navigation system. The position of a tracked instrument in relation to the patient's anatomy is shown on images of the patient, as the surgeon moves the instrument. The surgeon thus uses the system to 'navigate' the location
