Well, the biggest problem I am having switching to Blender so far is the lack of something between a group and a parent/child relationship.
When I create a group the group cannot be maintained as a physical entinty in terms of the basic transformation operations as far as I can tell. For this purpose the most useful thing I’ve found is created a group, finding it in the Outliner panel and then clicking through Select>All linked objects. Apart from that Groups are from what I can tell a completely informational structure and the manual says so.
Problem is, the parent child relationship also sucks. I might be wrong again here too, but I dont think think there is any support for instances of parents?
Anyway I think you know what I want and I there might even be something like that available. For example, I want to group 3 distinct mesh objects and duplicate them as a reference group. Furthermore, I would like to use this group in arrays and DupliFrames/DupliVertices operations. Maybe I’m missing something, let me know. Can I somehow put an object inside a nother object? Blah, I guess dummy objects are mainly used for this?
