3D model to Google earth

In order for your 3D design to drop at the same elevation as Google Earth the two elevations must match. The accuracy of the vertical information on Google Earth is not too great so if you have actual survey with .tin surfaces you based your design on, that vertical information may not match up exactly with Google Earth since it's more accurate.

If you wanted to "drop" your alignment/corridor so it does match up with google earth you can use the below Youtube video I found to create a terrain model based on Google Earth information. Once you have the terrain model, you can view your proposed alignment in relation to the terrain model and revise your elevations to fall onto it. Then you can export to the Google Earth format (.kmz) to view it in Google Earth.
