Details
Once you have imported a model using HPS::Exchange::File::Import(...) there is a mapping between HPS::Exchange::CADModel and the PRC in memory, and also between HPS::Exchange::CADModel and HPS::Model.
From a CADModel you can browse the structure to find HPS::Exchange::Component and for each component you can query:
The PRC entity pointer: GetExchangeEntity()
The KeyPath from HPS::Model : GetKeys()
HPS::Exchange::CADModel structure reproduce the PRC structure. It is a component tree.
Here is a representation of a simple PRC and how it would map with HOOPS Visualize data:
