The ODA Core Package serves as the foundation of our membership program. Available to all members—regardless of tier—it provides essential tools for engineering software development and is designed to deliver lasting value.

What sets the Core Package apart is not just the quality of its technology, but the way it evolves. Over time, we’ve consistently expanded this package with new functionality and even full-scale SDKs—without increasing membership costs. Here’s a look at the latest additions that enhance its value for desktop, web, and cloud workflows.
