emptying on particular section

[deep70]

Hello everyone,
I am a newly affiliated and supporter of creo 3.0, the version I use, I consider I create together with solidworks a step further than the remaining cads or modelers dir you want.
Now it happens to me that in view of section a particular represents me as emptied... I tried to do it three times but always with the same result... the technique is always the same used until now.
Now being a particular more than other representative (a transducer or inductive sensor) of the overall does not have an extreme importance... but does not give a correct view of the whole set.. This is a real sin.
Can you give me a logical explanation about this?
I place you some pictures and thank you in advance of your precious answers. .

in direct modeling the blank displayed parts are usually damaged and to repair them the easiest thing is to use the "check part" command that automatically repairs them; if you can't turn them into so-called "face parts", then at this point you need to find openings and insert faces.
