Prevent items from moving with terrain changes

[Larry_Sweeney]

I've added many different library items, architectural blocks, and moldings to the exterior of my design. With my design pretty much completed I now decided to add the terrain. As I'm adjusting the terrain elevation. I notice many of these items are moving with the terrain. There must be a setting for each of these items to prevent this, but I'm unable to come up with the solution yet. In the specification dialogue on the items in mention I use the elevation reference "finished floor", but it doesn't seem to matter where I have the "reference" the items move with the terrain.  I've tried doing a "search", but so far, I haven't found what I'm looking for.  Can anyone clue me in to my problem and the "cure"? As always, your time, patience and knowledge are always appreciated.

Any item that has an elevation set based on the terrain or 'floor' will move up / down with the terrain. All those object would need their elevations set as "Absolute".
