Abstract

In the CAD*I Database Group we handle geometry in the form of closed models as well as in the form of models divided into their single points, lines, directions, planar surfaces and topology. A closed model contains geometry in any format (in a second step also a part program or NC-data). It is impossible to look into the closed model, to recognize any structure in it. This view of data is used to archive and exchange data via a common database. To inform about the content, each closed model possesses a set of administrative data.
