visualization of results with hiding, volume works surface not

Dear,

If I want to do a visualization of the results, I need just a part of the total structure to be plotted.
Therefore I make a view and hide the parts which must not be visable.
When I enter a volume I see what I want to have only the visable part.
But as soon as I start to plot a surface or a slice it gives me the whole structure which is to complex to be interpretated by plotting.

How can I solve this problem, thanks in advance for the answers.
The hiding is working when doing volume plots but not when doing surface plots.

Regards
Hans
