Just a note that you can create and edit LOD (level of detail) for
Inventor (and VRML) files using SGI's Webspace Author. It also
has a polygon reduction editor that is pretty good, with which you
can generate the other nodes under an LOD.
If you want to get really hard-core, then Multigen is indeed
the tool for you, and it works well, but then it requires a
serious commitment of funds too. I believe they sell an
Inventor file reader as an option to the base system.
