This is a very very nice piece of software!
I will be doing around 40 pieces of furniture and rendering for a catalog once i get the translation ratio's figured out, everything I render ends up in environments with other pieces. And so the import scale has to be absolute or scalable in a way that I can control it.

Currently I import IGES files from SW.

Q1.
Does the .lwo exporter size the models based on mesh density or polygon count instead of actual size?

My room seems to be scaled larger at a point .2 than the chair at .2 upon export to .lwo?
I will double check everything, and get back to you.

thanks!
