3d transform tool

[sbedics]

I'm using the 3d transform tool to create a 3d cube.
When I finish the cube all the sides are transparent except for the bottom.
Does anyone know what I did wrong or how I could fix this?
Thanks,
Scott

You need to rotate your cube until all its sides appear in a shade of grey. Otherwise, only those greyed sides will be visible (in your case, the bottom one).

The tool to rotate it is on the 5th row, on the right.
