None of the created elements are visible in Floor Plan: 00 Foundation View. You may want to check the active view, its Parameters, and Visibility settings, as well as any Plan Regions and their settings.
You need to provide us with more information.
For example: what were you trying to place/create? is the visibilty for the category of that object turned on in the view (V/G overrides)? is it within the view range? etc.
What exactly are you trying to do - as stated you need to provice ore info.
