Tried using the cleanup plugin from ThomThom, thinking it may be due to the complexity of the model.
It really is not that complicated, Just some lattice work for a steel structure.
Other models with similar geometry have come in without the error report.
What is this attributed to. Texture, polycount or some other miscellaneous sketch up fail.
bring on revision 9.
Bring back the old way of getting places from Google Earth. (from the Earth UI) it was easier to navigate to locations that are out bush and not
on a road.
