I haven't know about the"Purge Unused" function until you showed me.
Yes, measure units are the same in the 3D MAX and SU (mm).

Well, if you modelled it in a way that it is messed up, an export will not help.

Did you model it at all? Is it an import? Can you share the file (upload as an attachment below the post where you are typing)

Yes, i modelled it by myself and with model in sketchup everything ok (i think so).
I attach rar archive with my model. Sorry for my english )

arch.rar
