IFCE EXPORT FAIL, PROBLEM ETC.

Dear All,

any reasons why export to IFC change my building to Star Wars spaceship?
It's really annoying because we can not cooperate with some companies that need this form of exchange.

I see no one got back to you on this.. I have been seeing the same issue for years now but ADSK seem to be ignoring the issue. Did you ever find a workaround?
