I have a subgrade plan with A LOT of existing contour lines. The program cannot handle the entire plan so I uploaded the section plans (qt 4) and did my cut fill take off on each section. Does anyone know if the completed projects can be stitched together? I did it this way also, because when you bring the project into the into the line loading feature and when I attempt to use a filter to extract that particular line too many show up and I am unable to use that feature. Along with the freezing, this has gotten old. I can use the calculations of each individual section but I want to be sure it is producing the same numbers as if they were all in one file. Hope that makes sense.
