When a project uses a projected Coordinate Reference System whose underlying geographic CRS is not WGS84 (for example, British National Grid / EPSG:27700), Revit displays the Survey Point (and location) latitude and longitude in that geographic datum (e.g. OSGB36).
While this behavior is technically correct, it is not obvious to users and can be misleading.
I presume most users would expect latitude and longitude values to be expressed in WGS84 because that is the standard used by Google Maps, GPS, web mapping applications and pretty much anything unless you explicitly set it to display non-WGS84 latitude/longitude (given the software even allows it).
Proposed solution
I propose Revit UI is standardized to display the latitude and longitude values in the UI (Survey Point, location) in WGS84.
Alternative could be also to display both native datum and WGS84 latitude and longitude; make the display CRS configurable; or at least label the non-WGS84 latitude and longitude to minimize confusion.
This would improve interoperability with common mapping tools, reduce user confusion, and make Revit's georeferencing workflow more intuitive.
