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= 2513.96
Area st 6+50 = 2560.24
cut/fill factor =1
the exaple is using the Averange end area formula
Volume = (A1+A2)/2) *L
L= [6+50] - [6+25] =25 foot
Volume =(2513.96+2560.24)/2 )* 25 = 63427.5 cubic foot
to cubic yard (as the report)
Volume * 0.037037037 = 2349.17 cubic yard.
But the report shown 2479.06 cubic yard
Same 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.
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.
