<p>In a data processing system having a plurality of CAD systems, an associative topology bus facilitates the management of heterogeneous assemblies of geometric objects. The constituent geometric objects can be geometric primitives or they can be assemblies, both homogeneous and heterogeneous. The associative topology bus enables a user of a CAD system operating on a heterogeneous assembly to recognize the existence of a change in a constituent component of that assembly and to do so in real time. The associative topology bus performs this task by augmenting the representation of the heterogeneous assembly with translated image models corresponding to each of the constituent CAD systems of the data processing system. Each translated image model is generated by operating on a master geometry representation of the heterogeneous assembly with a mapping table corresponding to each of the constituent CAD systems of the data processing system.</p> |
