Abstract
A CAD data object model and interface which captures and stores information relating to CAD data, including geometry, topology, design notes, and non-geometry drawing information, along with their associated relationships, is presented. The information and relationships are separately captured and accessible via a publicly defined interface. In one embodiment, the captured CAD data objects saved in separate relational database files, separated according to type. Because the CAD model objects are stored in a tool neutral persistent form, any application can access the information contained in those objects.
