CAD/CAM turnkey system CAM-X is designed to provide engineering manufacturing companies with the computer capability for drafting 3D design and NC production as well as handling management information. The system, developed by Ferranti Cetec, is being delivered to two companies involved in mechanical handling and pumping systems. Ferranti estimate hundreds of potential sites for CAM-X installation in the UK alone. A basic system will cost about £¼ million and include:
•

CADCENTRE news CADCENTRE has made the SDS drawing package and GINO-2D available for use on Motorola 6800 based microcomputers. Low maintenance costs have also led to a reduction in the cost of GINO-2D. Arrangements are being concluded with C & N Electrical Industries to manufacture CADCENTRE hardware. This would include the AGDT-Bugstore, RPC and RDSU. Bugstore is now almost 30 per cent cheaper; price reductions for the others should follow.

Basic graphics from Olivetti Demand fQr graphics has led Olivetti to produce the IGS 60 interactive graphics system based around their popular P6060 desktop minicomputer. Initial sales will be software only to present GTL (an NC part programming package) users but Bob Garrett, British Olivetti Marketing Manager, hopes the system will prove invaluable to architects, circuit designers and factory planners. The system comprises the P6060 computer, first marketed three years ago but kept up-to-date by the software operating system, the DSM 6660 raster-scan display and the IGS software, written in extended BASIC. The computer has an integral thermal printer, but interfaces to Benson or CalComp plotters will be available. The software, supplied on floppy disc, constructs images using elements (lines, circles, arcs, characters) and symbols (constructed from elements or other symbols). The demonstration circuit design program chooses sym-
bols from a menu. These can be positioned by x,y coordinates, the cursor (controlled by buttons on the keyboard) or can be connected to existing symbols. Transformations rotation about a point, scaling in the x and/ory direction and variable size definition - are all available. Symbols are automatically numbered and are erased by symbol and number. The software is primitive by today's standards - the perspective package does not have hidden-line removal and there is little the system can do but produce drawings, and coarse looking ones at that, which is not what CAD is all about. But rasterscan is predicted to be the display medium of the future and Olivetti do seem eager to listen to users, so the IGS60 is certainly worth investigating. The complete system costs about £12 500; software only about £1250. (British Ofivetti Limited, 30 -
