Hi Michael.....

Looks like it will working very nice.

>possibly these should get mapped to hierarchical groups when read in if I can get groups working.
It will perfect.

When export MoI to Iges, I wish the hierarchi of group inside MoI will be tight also.
So when open Iges from MoI in another software the hierarchi also there.

V2 or V3 is ok... :)

Thanks Michael... !
