Hi Michael,

I've noticed I can duplicate edges of (poly)surface using Join command in case the edges make up a proper chain or loop. Is it a side-effect of improving offset handling an edges?

Another thing. When I work with "no unit system" option and export an objects as IGES, MoI writes "inch-flag" into IGES file - so dimensions are interpreted as inches in another applications. Did you intend it in this way?
