Hi Michael,

I understand what you are trying to do with MoI and I agree that the layer systems you're showing there are restrictive, the reason why I couldn't understand where you were coming from, is because I was used to a whole different system.
The layer system that most other cad vendors have followed is from Autocad, which I don't think has ever evolved from the 2d world of past. I wonder how Autodesk handled Mechanical Desktop's layer system.

No doubt when Groups are implemented, MoI will be flexible enough to accommodate different ways of object organization, keep up the good work.

Cheers
