Autodesk University 2026 has just concluded. The headlines were mostly about AI, agents, and natural-language workflows, but I noticed a piece of news that is very significant for GIS professionals: Autodesk has finally unified the geolocation coordinate systems across Forma, Revit, and Civil 3D. For those who are often tormented by misaligned coordinates among BIM, municipal, and surveying teams, this is truly great news. After all these years, this annoying task, which is even more eye-straining and hand-straining than GIS vectorization, has finally seen a turning point. Today I will walk you through the details.
Unified Geolocation Engine
According to official statements, Forma, Revit, and Civil 3D will share a single geolocation engine and workflow, reducing manual coordinate transformations. In essence, this upgrades the existing coordinate system in Civil 3D into a shared service, led by the Civil 3D team and made available to Revit and Forma as well. Anyone who has worked on BIM-related projects knows that Revit previously had almost no complete capability of this kind. Currently, the Revit side is already available in connected workflows; further support will have to wait for official updates.
Autodesk CEO Andrew Anagnost said in an interview that the underlying technology mainly relies on Autodesk's own technology, while also being strongly influenced by partner Esri, and said that unifying coordinate systems is something Esri has long wanted to promote. Previously, inconsistent coordinate system support across products caused a great deal of invalid and tedious extra work. After the integration, it will deepen geospatial data connectivity with Fugro and Esri ArcGIS. For years, Autodesk and Esri have had inconsistent naming conventions for the same coordinate systems. Even a tiny difference in spaces or punctuation can cause import or export to fail. For this alone, the Autodesk team checked and optimized more than 2,000 items.
Remaining Issues
However, it is worth noting that this capability does not currently solve all problems at the surveying level once and for all. For example, elevation still depends on which datum the project uses, and long, narrow linear projects still need to address deformation from the curved Earth to a planar grid, among other issues. In addition, at present, interoperability is mainly within the Autodesk stack. Data interoperability with other software such as ArcGIS will require further testing.
Summary
Previously, in collaboration among BIM, municipal, and GIS teams, moving models between Autodesk and GIS software was a major headache. Coordinates were often misaligned, and someone had to repeatedly verify positions at the beginning and end of projects. Now that Forma, Revit, and Civil 3D share a geolocation engine, at least consistency can be maintained within Autodesk's own workflows. In the future, integration with GIS software is more likely, which is a real reduction in workload for GIS professionals who often work on BIM-oriented projects.
Finally, I want to say that in this era where AI is everywhere, established major vendors are still doing practical work. Compared with AI revolutionizing an industry today and a GIS agent tomorrow, this kind of old-fashioned update is actually refreshing.
