Merge Identical in 3DXchange 7.3 is deleting Mesh items
I loaded a Sketchup Model in 3DXchange 7.3 and first selected "Exclude .SKP Back Faces" and then "Merge Identical". Merge Identical deleted quite a lot of Mesh items. This does not happen with the same model in 3DXchange 6.5.
The 2 attached images show the issue, look carefully at the Window Frames and the Walkway Railing in the 3DXchange 7 image.
