EDX by Canam (Engineering Data Exchange)

Modeling steel connections in 3D is an essential step in reaching LOD400, but traditionally this task has been time-consuming, error-prone, and heavily reliant on manual processes. Every connection requires input from multiple disciplines, engineering, procurement, fabrication, and site installation, making it difficult to streamline across teams and systems. This complexity often leads to rework, inconsistent standards, and delays in project timelines. At Canam, we recognized that as projects become more complex and BIM adoption grows, the traditional methods needed to be optimized, standardized and automated. We needed a scalable and repeatable way to accelerate connection modeling while improving precision and reducing human input. The challenge was not just to automate geometry, but to create a system smart enough to factor in fabrication and engineering realities, bolt quantities, weld size, and many more, so the result would be directly usable for both drafting and downstream processes. That led to the development of EDX, a tool designed to unify engineering calculations and 3D modeling, while preserving the flexibility required for real-world projects.

EDX bridges the gap between engineering calculations and 3D modeling. The process begins with a Tekla model at LOD300, containing framing geometry and design intent. Additional inputs—such as loads, special requirements, or erection constraints—are provided through structured reports. This data is then processed through Canam’s internal engineering calculation tables (based in Excel), where the required steel connection is determined. EDX then automatically pushes the calculated data—bolt counts, weld sizes, plate dimensions, etc.—back into the Tekla model, generating the complete 3D connection geometry at LOD400. This seamless loop transforms what used to be a multi-step, disconnected process into a unified digital workflow. Engineers no longer need to re-express calculations manually, and drafters receive fully formed, fabricable connections with all relevant attributes embedded. Not only does this reduce risk of error and rework, but it also speeds up both engineering and drafting phases. As a result, teams can focus on reviewing quality and handling edge cases instead of redrawing routine connection types.
