Tekla Structures 2019i |verified| Jun 2026

Prior to IFC4, data exchange often resulted in "dumb" geometry—shapes that looked right but lacked engineering data. With , the export of IFC4 Reference View models meant that structural engineers could share their models with architects using Revit or ArchiCAD without losing the intelligence of the data.

Released as a bridge between the major 2019 version and the eventual 2020 rollout, represents a sweet spot for many fabrication and detailing firms. It offers significant performance boosts, quality-of-life improvements, and interoperability fixes without the "bleeding-edge" instability of a .0 release.

Released as an intermediate yet substantial update to the 2019 lifecycle, the 2019i version represented a pivotal moment for the industry. It was a release that prioritized workflow fluidity, collaboration across borders, and the critical need for "constructable" data. This article takes an in-depth look at Tekla Structures 2019i, exploring its features, improvements, and enduring relevance in the AEC (Architecture, Engineering, and Construction) industry. Tekla Structures 2019i

⭐⭐⭐⭐ (4/5 stars)

For the uninitiated, Tekla Structures is a BIM software tool that allows users to create and manage structurally accurate, data-rich 3D models. It is the industry standard for steel and concrete detailing, capable of handling the most complex geometries found in stadiums, skyscrapers, and offshore structures. Prior to IFC4, data exchange often resulted in

Professional structural detailers needing reliability. Skip if: You’re on 2018i and happy, or if you want cutting-edge features like real-time clash detection.

The "i" in stands for "international" or "interim," denoting a version that refines the core architecture of the main 2019 release. However, to dismiss it as a mere patch would be a disservice. Trimble, the parent company, utilized the 2019i release to introduce significant enhancements in interoperability and user interface optimization, ensuring that the software remained agile in an increasingly collaborative digital construction environment.

The designation is crucial. In Trimble’s naming convention, the "i" stands for "intermediate." These releases focus on refinement. While Tekla Structures 2019 introduced new workflows (like the Ribbon interface and drawing wizards), version 2019i focused on making those workflows fast and stable .
