Has anyone gotten the MakeFlatSnapshot command to work?  I have some 3d DWG files that I want to flatten out into 2d views, but the command doesn't seem to work.

It says there's nothing found to project.  Or if I explode the model before running MakeFlatSnapshot, it'll pretend to run but not produce any results.  Even if I use the export to file option, it just produces a 24kb file that doesn't contain anything.  I zoom extents and nothing is there.
