Michael,

I would really like something to be able to group objects together and handle them as a unit. I understand this can become quite complex but I'd be happy even with something relatively simple.

I suppose that ideally a "group" would allow for a group of groups where each individual object and subgroup keeps it's properties. A named group, say a "door" with all of its parts could be tagged as the left, right or whatever "door" and not necessarly become a distinct object. A mechanism to distinguish type of "copies" of a group, say a "cloned group" would be an exact duplicate of the original this would allow the possiblility of editing individual part of a group and update all "cloned group" automatically. Another type of group could be allowed such that edits are not updated automatically but on demand, here I'm thinking of my left and right door again which may not be 100% symmetrical, say for example that the right door as an additional part that serve as a stopper for the left door but beside that part every thing else is symmetrical so edits could apply only to corresponding parts in those groups. Say for these doors again, this time not only the right door as an additional part but some parts are could be distinguish further like say a left and a right hinge and of course at this time we could setup a different style to the hardware parts of the door such that it's easier apply the proper material later on. One last thing I'm thinking of for my ideal doors "groups" again, it would be something like tagging individual part in somekind of hiearchy say

door.right -> right-hinge.001.brass or right-hinge.top.brass
right-hinge.002.brass or right-hinge.middle.brass
right-hinge.003.brass or right-hinge.bottom.brass
crossmember. top.002.walnut *** this part is a mirrored copy of door.left -> crossmember.top.001.walnut
...
panel.top.002.walnut *** this part is a mirrored copy of door.left -> door.top.001.walnut
...
etc.

Then of course, some means to create a bill of material for these doors. This could go on and on but as I said earlier, this would be the "ideal" group thing for me, maybe in another life.

For now I'd be happy with a much simpler grouping mechanism that would be useful both in Moi and on mesh exports.

Thanks,
Felix
