This 3D model was originally created with Sketchup 7 and then converted to all other 3D formats. Native format is .skp 3dsmax scene is 3ds Max 2016 version, rendered with Vray 3.00 The Hardin County Justice Center in Elizabethtown, Kentucky. This is just the old model from a couple of years ago placed in Google Earth. The model is flying a little at one side of the building but to be honest I don't think it's worth the time or energy to sort out a base for it. If it's not accepted for the Buildings layer then so be it. In my opinion the terrain feature of GE is far more trouble than it's worth.
