Autodesk Quantity Takeoff

[#1]

When I go to create a volume report I get no volume everytime.....

I have a design profile, an assembly, a corridor, a corridor surface, an existing surface, sample lines sampling the design corridor and the existing surface, and I created section views and each section looks correct.

I went to compute materials, selected earthworks, selected my existing surface and my corridor surface, checked the condition to be sure it was selecting the area below the existing and above the design, clicked apply. Then tryed to run a volume report.....and I get nothing.

I'm not sure what I'm missing. I have done this once before on another project and I can't see any difference between the two??

Thanks for the help.
