Title: An experimental authoring system for CAD applications
Author: Yakoob, Nisar Ahmed
Abstract: Writing software for interactive CAD systems is costly , inflexible and difficult - It requires many man years to develop a fool free interactive system because the dialog between the user and the system is very conplex . Authoring systems reduce the investment needed to produce applications by providing a set of tools suited to the domain of those applications . This thesis investigates how an engineering workstation , the Unix environment and an engineering database system can be combined to create an authoring system for CAD applications . The terra authoring system for CAD application is used in this thesis to mean a system for development of CAD applications . The investigation was performed by implementing a simple integrated circuit layout application . Engineering workstations are powerful single user computers . A typical station will have its own mass storage device , a high speed interface to other stations and a medium resolution graphics screen . Unix is an operating system which allows programs that were written independently to communicate using pipes , filters and mailboxes - An engineering database system provides a set of tools for creating , maintaining and mutating the data in a CAD application . A system which combines these tools should considerably reduce the software investment needed to produce a CAD application .
