Quick Volume of a surface?

[ChristopherVol]

My coworker was saying in the old ACAD he was able to list the properties of a surface and it would give a volume.  Is it possible to do this is the current Civil 3D?    What we do now is: we have a pile of dirt.  We take shots all the way around the bottom and then on the pile and at the top.  We make one surface using the outer bottom shots to create a bottom of the pile.  We then use all the shots to create the pile.  We then do a volume using the the 2 surfaces.  Is there a quicker way?

Use the command REPORTSURFACEVOLUME.

A Civil3d surface is never a closed volume. That would violate the TIN algorithm.

you have to compare one surface to another. Typically EG vs FG

in a volume surface. This does the integration between two curves

Hi @ToddRogers-WPM  what does that compare to? The lowest elevation of the pile?

[ToddRogers-WPM]

It's the old volumes dialog box. Saves you from having to create a volume surface. It's only for calculating the volume.

That still required two surfaces being made.  Like when you connect a polyline and close it, properties gives you a perimeter and area.  Nothing will do that for one surface?

Go back to calculus 102 volume= sum of the area between two curves
