Problem
Unable to align main dgn file with attached referenced dgn file.
Steps of reproduction
Referenced file does not align with main dgn file even though we have attached reference file with “geographical-reprojected” Orientation.
Solution
In Spain the general ED50 derived Geographic Coordinate Systems should never be used. The general ED50 GCSs are meant to provide a global fit over Europe but are totally imprecise on a local level.
The user should set his GCS to the ED50-IGN.ES-UTM30 Geographic Coordinate System and will then obtain a perfect match between the two files.
