Building more advanced Inventor automation requires more than knowing how to write the code. You also need to understand the objects you’re working with and how they relate to one another inside Inventor.

In this Autodesk Inventor Automation Academy session, we take a closer look at the Inventor API Object Model and some of the concepts you’ll encounter when developing more sophisticated automation.

You’ll explore component occurrences, component definitions, documents, proxies, and the relationships between them. Understanding these distinctions can make it easier to navigate the API, troubleshoot your applications, and build a stronger foundation for more advanced automation projects.

  • How the Inventor API Object Model is structured
  • The relationship between documents, definitions, and occurrences
  • How component occurrences differ from component definitions
  • Why proxies are needed and how they fit into the Object Model
  • How understanding object relationships helps with more advanced Inventor automation
