sectional solids

[tower]

hi to all, use autocad 2012 I built a solid and I dissected it, I would need to treat the sectioned part in the layout so that I can then print it and see it but the program does not realize it, throws me a message: "Impossible to define a closed contour." Is there a possibility to realize it? but above all, can you do it with solids? (on the net there are mechanical drawings sectioned and drawn) thanks in advance to those who want to help me.
