# How do I join several objects into one?

I'm creating side skirts for a truck and I am duplicating the frames I want. The problem is it's making the duplicated object into another object. How do I put it into the same one?

• I'm not sure what you are asking. Do you want to make those into one object? (Ctrl+J) – gandalf3 Dec 30 '13 at 0:31
• I want to make each model into only one layer for each of them – user2004 Dec 30 '13 at 0:36
• for example I have model6.000 and model6.10 I want to make it so the are both within model6.10 only – user2004 Dec 30 '13 at 0:37
• Try selecting them both (selecting model6.10 last) and pressing Ctrl+J – gandalf3 Dec 30 '13 at 0:38
• it only lets me select one object – user2004 Dec 30 '13 at 0:41
