After finish fuselages work, I will continue on tail but before do anything, I want you to choose menu > Panel and select Object Panel to open an Object Panel. You will see Object Panel appear on screen. MetaSeq can work in own object like layer in another graphic program. Obiect panel can help you to split design into section like Fuselages section, Wings section or Tails section. Object Panel has some button you need to know as New, Clone, Delete, Prop, Misc each button have meaning itself, New use to create a new object, Clone use to duplicate object into new object, Delete use to remove no need object, Prop is a property of current onject. Eye icon in front of each object is use for hide or unhide that object, key icon in front of each object use for lock or unlock object.
Open your Object Panel then double click at Obj1 (Double click at objects name is a fast way to go to objects property) and rename from Obj1 into Fuselage then close object property windows, Click at New button to create a new object, Double click at new object you create and rename to Tail.
