Setup for CAD style 2D/3D sectioning in Blender 2.62, intended mostly for technical models, renderings and animations.
Example animation created with this file:

To control both 2D and 3D section just move or rotate blue controler bone.
Important notices:
fast computer hardware is required esp. when realtime sectioning is done in the viewport
Blender 2.62 or newer required due to boolean library
Nice preset, thanks)
