Display surfaces in section view on drawing

Hi folks
I have saved some of my assemblies as parts with only exterior faces to keep
the size and loading time down when I use them in bigger assys. I then
brings these parts into for example a plant layout. Problem comes when I
want to make section views in the drawing, no surfaces are visible. I found
that I should be able to bring in surfaces by "insert model items/reference
geometri/surfaces" but it doesn't seem to work. I tried a number of diffeent
settings without luck. Anybody know of a way to do this....I can highlight
the part in the tree and see it like that in the drawing view , but no more.
