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
Laboratory Unit for Computer Assisted Surgery Laboratory Unit for Computer Assisted Surgery Laboratory Unit for Computer Assisted Surgery is a system used for virtual surgical planning. Starting with 1998, LUCAS was developed at the University of Regensburg, Germany, with the support of the Carl Zeiss Company. The resulting surgical planning is then reproduced onto the patient by using a navigation system. In fact, LUCAS is integrated into the same platform together with the Surgical Segment Navigator (SSN), the Surgical Tool Navigator (STN), the Surgical Microscope Navigator (SMN) and the 6DOF Manipulator (or, in German, "Mehrkoordinatenmanipulator" - MKM), also from the Carl Zeiss Company.
