Model Properties and Data Exchange API are recent addition to Forge family. They allow us to access design data in more controlled manner, such as by filtering, searching and comparing models between versions. Instead of sending the entire model, you can select only the portion that your collaborator needs. Together with Model Derivatives and Design Automation API, we now have more options to access design data. However, can you tell which one to use for your specific needs? Do you know differences among those APIs? In this session, we will introduce you to two new recently added APIs: Model Properties and Data Exchange API. We will then compare various options we have to access design data. We will show the examples of use cases, and discuss potential application areas that were not possible till now.
