1. SCDM/DM: A BOI body must not share topology with the model itself. Use a unique name for each BOI body. 2. SCDM/DM: Create a named selection from faces of the BOI body (not from the body itself). Create different named selections for faces of different BOI bodies. 3. FM workflow: All imported BOI labels must be defined in a local sizing. Multiple BOI labels in one local sizing is ok.
