This thread is supposed to be a help for Michael... I believe that almost all of us have some experience with other 3d apps.
The question is:
"WHAT METHOD DO YOU PREFER FOR OBJECT HANDLING AND GROUPING?"
For example... Do you want a layering system? Do you want object names and group names?
Do you want a simple object hierarchy tree?
My experience is from AutoCAD, Revit and a little of Max. They use different grouping and naming methods.

I start this thread because it is very difficult for me to tell what method is best for MoI.

Please write your opinion, avoid -if possible- to answer to everyone else unless there is something important to clarify.
Let's keep this thread as small and readable as possible. I would make a poll if there was such possibility.

I have to go immediately so I will write my opinion later...
