Well my problem is I can't section my 3d model with 2 planes instead of 1.  I have a cyclindrical drawing ang I'm trying to section a pie shaped section out of it.  Maybe even slice a pie section out of the model when I'm finished.  Everytime I section I get 1 plane thats cut all the way through the 3d-model.  the cyclinder is extruded on the z axis.  The question is do I section twice or is there another command I can use to cut the pie shape out of my cylinder.

Thanks for any help.  Its greatly appreciated
