As I said, I don't think there is anything wrong with adding meshes, you could
even combine a mesh and CSG for certain purposes, or multiple meshes.  Think
about the fan idea: make the housing, base and fan blade from seperate meshes,
they could then be combined in a macro with appropriate variables to control
the fan spin and housing oscillation for specific scenes, motion blur,
animation etc., things that wouldn't be simple with a single mesh object.
