Gable CAD Gable CAD Gable CAD, or Gable 4D Series, was a British architectural computer-aided design package initially developed in the early 1980s. Gable CAD was developed at the University of Sheffield in the mid-1980s under the leadership of Professor Bryan Lawson. It was spun out into Gable CAD Systems Limited (incorporated in 1984) and retained links with the university until its demise in 1996 when a court order was made for compulsory winding up. An early building information modeling application, Gable CAD was an advanced 2D and 3D design package with different modules, and was operated via a Windows-style interface and
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
