The present disclosure features systems and methods for maintaining consistency of a CAD model across a plurality of homogenous or heterogeneous applications across one or more computing devices and used by one or more users. The systems include a common data model, comprising chapters of different information items to describe various aspects of the CAD model, and lightweight change instructions representative of modifications made by a user to a chapter of the CAD model. By utilizing a common data model and difference-based change instructions, a plurality of users may concurrently collaborate on the design of a CAD model, or a single user may utilize a plurality of applications of a CAD suite efficiently and with an enhanced user experience.

Methods and systems for managing synchronization of a plurality of information items of a computer-aided design data model

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.
