Strip Area Volume

I have used many other takeoff programs in the past. It is common that once an area with a specified subgrade depth is created, the cut/fill of the area will be shown automatically in the report.
It is similar to use the Strip method to create the region in this program; however, the volume cannot be shown in the report. A volume region will need to be created in order to compute the volume. This program tries to be precise not to have any region or boundary overlapping while other programs do not have this restriction which may generate a slightly different overall result when adding the areas together. This small margin of error is acceptable in terms of earthworks estimation. 

I have done two projects with this program, one has only 3 Strip regions and other has more than 20. The simple one I could fix the region error easily; but the complex one took me a lot of time to fix these errors even though all the lines are snapped together. I have ended up removing one Strip region.

Creating the volume region is also a challenge as mentioned in other Forum.

Please advise.
