Creating a Data Exchange file from a published Revit model initially seemed like a great idea. In fact, the entire concept of Data Exchange, even when used within its native software, appears very promising. However, it currently does not extract all parameters or properties from the model. I raised a case with Autodesk Support regarding this issue, but was redirected to this Idea Board. These missing parameters are, at present, by design. It seems the development team is aware of the limitation and plans to address it in the future. As I understand it, the Data Exchange format currently focuses primarily on geometry rather than parameters, as it cannot guarantee the inclusion of properties. But isn’t that the core purpose of having data-rich Data Exchange files? My formal request: Please enable the extraction of all parameters into the Data Exchange, both when created via the ACC viewer and when generated within the native software. This would make Data Exchange files reliable for any use. At present, Data Exchange is not practical because the missing parameters are unpredictable, making it impossible to know which data will be excluded.
