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 position of the bone segment are: symmetry with the opposite side, the continuity of the normal bone contours, or the normal volume of an anatomical region (such as the Orbit. Afterwards, a textured final image is rendered. The calculated vectors for the bone segment repositioning, together with the whole virtual model are finally transferred to the Surgical Segment Navigator. 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
