Running the Register with Geodatabase tool against a SDO_GEOMETRY table with z or m coordinates fails to draw true curves.

After review by the development team, it has been determined that this issue is related to a known limitation with the software that lies outside of Esri's control. The issue's Additional Information section may contain further explanation.
After registration with the geodatabase when the user accesses this feature class in ArcMap, it is densified (as seen in an edit session.)
The reason for this is that for ArcMap to recognize these curves (three dimensional geometry), the curves need to be generated within ArcMap. Only then ArcMap can store the geometry (with curves) in the ‘SE_ANNO_CAD_DATA’ column. This information cannot be obtained from an SDO_Geometry shape with measures.
ArcMap is able to recognize these curves only from a 2-D shape, without measures or z values.
