how export 360 with 3D object?

The way After Effects' 3D works (as I understand it) is that it actually creates 6 duplicate comps with cameras pointed in the different directions.  When you add anything to the main comp, you need to run the update process so that it re-duplicates the other comps.  It may be that your system cannot cope with 6 3D models running.  In which case, you can render out each support comp individually, then bring them back into the project.  

Although another explanation might be the error message you're getting (orange bar) which suggests there are 10 expressions failing to run.
