Hi Anis, I'm getting close to working on groups.

> maybe Group can solve this case?

Well, groups in Moi would provide a good interface for how to set up the hierarchies.

But having a good interface access point does not automatically make functions appear for file export at the same time.

I'm still not sure to what extent the STEP library that I use is set up to control hierarchies in the generated STEP file. I think it may not currently have a lot in this area yet.

In fact these last tests by Danny seems to indicate that the hope I had for just putting the group information into object names separated by : characters is not going to do anything at all.
