Can't add objects to scene I'm doing a really basic outline of a park scene, and i'm trying to add a circular plane so I can begin to model my amphitheater. For some reason, when I hit 'Space' and add the circle, nothing shows up. Same for appending an object. I have also tried centering it with Shift+W.

Here is the link to the .blend file. I need as much help as possible; I have a project including this I need to turn in tomorrow. Thanks for any help or insight.
The issue is that the active layer is not the one that is visible. So your objects are being created in layer 9 instead of layer 1.



To make layer one be the active layer press 1



To see the contents of both layers press 1 and Shift 9
