You can only remove object symbols that are not used in the model. If you try to remove object symbols that are used in the model, the modeling toolbar will be split at the end. The object symbols that you want to remove from the modeling toolbar but that are still used in the model are listed below the separator bar. Object symbols that are placed below the separator bar will automatically be removed as soon as the last object with this symbol is deleted from the modeling area.
