Hi all!
I am from Hungary so my eanglish is not the best! Sorry
I have a problem..
I whant to calculate the fill of a pit. I have mayd two survays and maked 2 maps from them , one(upper) when the terrain was not touched, second(lower) time when they had taken out some humus and sand. I have the DTM menu i have set up the two survays
extrath-graphics then build - triangles then edit-trangles ( i have taken out the not good lines) then analysis-volumes- tin to tin i have strated with the upper to the lower. I have got a total cut and total fill m3 . But somebody teld me thay shoud be equal.. is this rigth? And how can that be rigth?
Becouse i got this total cut :16269,454m3 total fill:49430,395m3
And what does this mean? they have put some sand on the first survay?
Thank you for the help folks!!!!!!!!!!
Oh and another.. I have a depo. I say it 180000m3 and another landsurvayor told me it just 105000m3 and we whas working with the same survays... how can this happen? I have make a mistake somewhear? i will put this up to!
I will put them on my download area here the two dwg-s if some whould be so kind to calculate it for me again to see what whoes the problem ..if there was a problem:)
Realy thans for the help
Michael Gilham: The Volume dialog works like this: We begin at the "From" Surface (TIN). In your case, this the surface before the excavation occured. We then compare it to the "To" Surface. In your case, this is the second surface created after excavation. The surfaces are compared over the total minimum intersected area... basically, the co-incident plan boundaries of the 2 surfaces is analyzed.

CR: I like to have this co-incident plan boundaries as a result of the volume calc, how can I get it quick and easy?

Frank,
towards the bottom of the dialog is a group box titled "Volume Polygons".
By default, the first option (Display Only) is enabled.
Disable this option, set the desired graphical parameters in the sample graphic and click Process.
A graphical shape will be drawn and sustained in the DGN that is the co-incident boundary mentioned earlier.

Oh sorry, I thougt you were talking about InRoads, there I haven't this options.
