I need to know how to cut a shape up into separate sections, for example, how can I cut a cylinder in half, so that I can animate the different sections pivot points, thus the cylinder opens out.

With a cube before I've been able to just duplicate it 7 times, however with a cylinder I need it split in half and into other smaller sections.

There are several ways to do so. As you mentioned, if you really need to fill sections after cutting, I would suggest a tricky way:

  1. Create a mesh that contains expected sections. Add Solidify modifier to this mesh, set Thickness to 0.00001. You can leave other options as default;
  2. Add Boolean modifier to cylinder, set Operation to Difference, and Object to the section mesh. Then press Apply;
  3. Delete the section mesh, Tab into cylinder object, select all elements, P>By loose parts to separate each sections apart;
  4. If you want to recalculate their origins, just ShiftCtrlAltC > Origin to Geometry.

enter image description here

P.S.: In the latest version (the coming 2.70), Boolean modifier supports ngons, which will generate better and cleaner result.
