Caddie (CAD system) Caddie (CAD system) Caddie is a mid-range computer-assisted draughting (CAD) software package for 2D and 3D design. It is used primarily by architects, but has tools for surveyors and mechanical, civil and construction engineers. It was initially designed as an electronic drawing board, using concepts and tools clearly related to a physical board. Caddie requires a USB dongle. or software activation. Without the dongle or activation, the program can be used as a viewer and plot station for any DWG drawings, but it can't save drawings after the 14-day evaluation has expired. Caddie works on Windows XP, Windows Vista, Windows
Computer-assisted surgery time. There are several disadvantages of computer-assisted surgery. A major disadvantage of this system is their cost. With a price tag of a million dollars , their cost is nearly prohibitive. Some people believe that improvements in technology, such as haptics, increased processor speeds, and more complex and capable software will increase the cost of these systems. Another disadvantage is the size of these systems. These systems have relatively large footprints and relatively cumbersome robotic arms. This is an important disadvantage in today's already crowded-operating rooms. It may be difficult for both the surgical team and the robot to fit
