Exporting DGN to Google Earth doesn't come up in the right place (SS3)

Question

Hi All, 
 I'm having an issue exporting DGN to Google Earth. I red all the other forums and did what others said as using the Geographic Coordinate System. I'm choosing the correct GCS but the line work doesn't come up in the exact place. It is usually shifted to the left 20-30ft. 
 I found a solution by using placemarks, but since I work in Road projects I have to place a lot of placemarks and it is time consuming. 
 The easiest way is just using the GCS from the library. Maybe I'm doing something wrong here. 
 Anyone out there that can help? 
 Thanks!

most countries have a online national survey dept with Permanent survey markers and their coordinates as well as cadaster files 
 if you know here your site is you can find this data on line download the cadaster file in dgn set its CGS just in case 
 then plot the survey marks onto it with say put circles and keyin xy= easting coord, northing coord 
 the coord you get from the web site... 
 then ref attach your original data to the down loaded file and see if any object line up... if not go back to your original file and plot the survey marks again manually in this file then try google map to place the survey marks from both files if they dont land exactly the same then you first file is at fault and is not in the right place 
 to try to fx this ref attach the modified cadaster file with the survey marks ( labelled by hand too) into your original file now try to move rotate scale whatever the active data original file data to match the ref file survey marks... now save and tell it to use the gcs of choice but dont choose to correct the data .. 
 your files should now match and so they should in google earth...
