A procedural interface to CAD data based on EDIF

EDIF is a data interchange format which currently provides a solution to the problem of data transfer between proprietary CAD systems. This paper considers how a procedural interface to a CAD system may be built upon the underlying data model of EDIF. It outlines the procedural interface and describes how a novel implementation has allowed access to, and extension of, the database to be particularly flexible, as well as following data management functions to be dynamically incorporated into it.<
