However, I tried to export my 'boolean' sofa that way and objects made with primitives but using the boolean method don't work-they don't get that E that you need to do the cntrl-click. I exported other things fine using that method (the symmetrical lattice is considered a terrain though, isn't it--or are we just out of sequence on this thread-Cybor, you probably meant your answer for ScottK's post).
