>re: layers staying in place - yup that was a function I added in for MoI so that when you open up a .3dm file from Rhino, things that MoI does not understand or work on directly are still stored and written back to the file when you save out again.

A-ha! So if its exactly the same going out as it was coming in, the objects props are preserved. I didnt know that. :-)
