Regenerate option?

 From:  Fitz (3DARTZ)
Hey guys,
is there any sort of regenerate or rebuild option in MOI?
Here is what I did, I made a model that is like a remote control.
But I was not too careful when I built the body, so one side was not identical to the other.
after I finished building the whole model, I cut it in half and deleted one side.
then I mirrored and "joined' the to halves together.
Upon export and import to my 3d rendering app, the side that was mirrored and attached to the
original side has aritfacts all over it.

thanks for any info,
Mike Fitz
