Objective
The objective of this project is to develop a family of consistent, compatible standardised interfaces for CAD, allowing:
-representation of 2-D and 3-D geometrical models of CAD design objects
-archiving and retrieval of these models by various CAD/CAM systems
-exchange of such models over networks
-storage of parametrised part libraries in databases connected to networks
-access to such libraries from various CAD/CAM systems
-use of advanced modelling techniques for model generation
-standardised application of different finite element model analysis programs
-comparison of experimental and analytical dynamic analysis results
-dynamic model optimisation resulting from experimental and analytical analysis.
The availability of a standard interface will facilitate the free flow of geometrical design data between different CAD systems without expensive conversion and data restructuring. It will also permit CAD systems to be interfaced with Computer-aided Engineering systems, such as those used for the static and dynamic analysis of structures.

It will also permit CAD systems to be interfaced with computer aided engineering systems, such as those used for the static and dynamic analysis of structures. The project's contributions include the neutral file for CAD geometry (covering solids, wireframes and free-form surfaces), a high-level data specification language (HDSL), and an interface to finite element analysis systems. A wide range of CAD interface pre- and post-processors and dynamic analysis systems developed within the project are available.
The project has produced the main portions of the projected international STEP standard, adopted as a draft proposal by ISO TC184 SC4 in December 1988. CAD*I contributions include the neutral file for CAD geometry (covering solids, wireframes and free-form surfaces), a high-level data specification language (HDSL), and an interface to finite element analysis systems. Many partners have incorporated the interface into commercial products, such as Leuven Measurement and Systems (CADA LINK, CADA TEST and CADA MODAL), which has implemented the interface in a product for the experimental testing of dynamic behaviour in the development of machine-tools, cars and aircraft. BMW has implemented the standard interface internally.
A wide range of CAD interface pre- and post-processors and dynamic analysis systems developed within the project are available. KfK is providing CAD geometry interface software to a German CAD vendor for incorporation in marketable products.
Programs to perform syntactical and semantic checks (SYNTAX) and statistical analyses (STATISTIC) of IGES files have been licensed by BMW.
