CAD International Directory 1986 is part of a series of directories of products and suppliers in the field of computer-aided design (CAD). It aims to be an invaluable buyer's guide and a useful all-year-round reference book that tells users who sells what in their field of interest and where to contact them. The directory begins with four chapters that survey the current state of the CAD field and discuss developments in CAD and computer-aided engineering (CAE); factors to consider in workstation selection; and future developments in the CAD environment. The remainder of the book contains the directory of CAD products and services, which is divided into eight sections. All entries in every section but Section 1 are listed and indexed in alphabetical order of supplier. The software section is listed in alphabetical order of program name and is indexed by both supplier and program name. The suppliers' names, addresses, telephone and telex numbers are listed at the end of the directory.
