Well, if you want to go the NURBS route, and don't want to deal with the 6 planes that Mike mentioned, you could try this:

1. Draw a cubic curve in the shape you need to define the top/bottom vertices and edge....basically a "C" shape....straight except for little curved areas where the corners will be...2-3 pts for the corners will be fine.

2. Go into your Revolve options and choose "linear." Revolve 360 degrees with 4 segments. This will give you box-shape that is all one object.

3. To make it more dice shaped, in the channel box, switch the revolved surface to cubic and add more segments (12-16) which will give you a cylinder shape. Then in the top view start scaling hulls into the shape of the die.

If all this is too much, I'd just stick with the bevelled poly cube and texture it with bump maps for the dots.
