[Inroads v8i SS1] clipped components are not displayed

hi,

 I work with a few corridors and In roadway designer I create a single surface built of these corridors.  In clipping options I set one corridor clipping another - as a result I get a designed surface. I am satisfied with this surface, howewer when I displayed cross sections I noticed that clipped components are not displayed. I can display all the components of the clipping corridor but clipped components of the other corridor are not displayed. Since I cannot display them with Surface/View components, I guess clliped components were deleted.

Is there a way to display clipped components in plan view and cross sections? How can I include these components in volume calculations?

Thanks in advance for your help.

Adam.
