Claris CAD 1k of disk space is required. This is due to a limitation of saving to large size, HFS+ formatted disks. One can save to a floppy disk or small RAM disk as a workaround, or use the "Save As..." command, renaming the file in the process. Claris CAD Claris CAD was a two-dimensional computer-aided design program for Apple Inc. Macintosh. Claris CAD was developed in 1988 by Claris Corporation in a joint effort with Craig S. Young of Computer Aided Systems for Engineering (CASE). It was based on MacDraw II and Young's earlier CAD application, "EZ-Draft". Version 1 was released
Computer-assisted surgery Computer-assisted surgery Computer-assisted surgery (CAS) represents a surgical concept and set of methods, that use computer technology for surgical planning, and for guiding or performing surgical interventions. CAS is also known as computer-aided surgery, computer-assisted intervention, image-guided surgery and surgical navigation, but these are terms that are more or less synonymous with CAS. CAS has been a leading factor in the development of robotic surgery. The most important component for CAS is the development of an accurate model of the patient. This can be conducted through a number of medical imaging technologies including CT, MRI, x-rays, ultrasound plus many more.
