I bought a week ago, and now buy a plug-in for make house (architools)
I have truespace 7.5, but carrara is more easy to use
and more, more stable.
Can export to .fbx (no import well from med)
To .x (I not chek to much the import in med)
and .3ds (perfect import in med)
and other formats but I tell that by use with med.
Really easy use have a rendering engine high speed at that quality
The procedures textures(glass, metal incredibles) are very easy to setup and can convert to ordinary textures.
Is a release comming at the end of this moth, for correct the bug in the exports and other minus bugs (how .fbx)
But for me by the moment work perfect
I recomend The architools plug in is very easy and speed to make house with that
