Hi everyone, My Name is Marcelo, Im from Argentina.
I have a problem with cut/fill volume calculations.(between the difference of the volume report and the calculation by hand)so I followed the Exercise 3: Generating a Volume Report - earthworks-2.dwg , from the help directory (civil 3d 2011).and I found differences there too, I think that some volume sections are not right,(ie 6+50, 6+75 to 8+50,etc), or I´m missing something.?An station exaple:Area st 6+25= 2513.96Area st 6+50 = 2560.24cut/fill factor =1the exaple is using the Averange end area formulaVolume = (A1+A2)/2) *L so:L= [6+50] - [6+25] =25 footVolume =(2513.96+2560.24)/2 )* 25 = 63427.5 cubic footto cubic yard (as the report)Volume * 0.037037037 = 2349.17 cubic yard.But the report shown 2479.06 cubic yardSame with other stations, and metrics. What Im doing wrong? I missing something?I tried this in civil 3d 2011service pack2 on a W7 64bits.thanks in advance.Marcelo
You have used the AVERAGE END METHOD to calculate your quantity.
Perhaps the computer is using the PRISMOIDAL METHOD. I believe you have a choice.
Bill,Thanks for answering! I really appreciate you taking time to answer my question.I checked that, when I select the average end area method the calculations are wrong (as I describe above), but with prismodial method the calculations are ok.
