Solid model of stockpile

[Anonymous]

I have created a model of a stockpile and base for volume purposes. The client has given me density readings from boreholes on the stock and asked if I can provide a model showing these densities as a 3D solid. Best way of explaining is that he would like to see a view of the stock as if it were a cake with a quarter slice taken out and the filling in view.  I may have started off on the wrong track but currently have the density readings as a series of 3D solids based on depth/density and these are all set to the stock boundary so I would now like to slice these solids to the stock surface but cannot seem to be able to, the stock surface was a triangulation (3D faces) that I have now converted to solid and joined in union but this surface seems to be too complex to use to slice. 

Hopefully someone can tell me either I have gone off at the wrong approach or this is the right way with some kind of fix.

For info I am working in Civil 2010.

Not sure what you mean by "density readings from boreholes"

In the case of this stock it is coal and the client has taken samples at every 0.5m depth and the values he has given me are described as Density (kg/m3)

Hmmmm....I'm not particulary familiar with the use of vanilla CAD surfaces and solids.

I would probably have approached it in slightly different way and created Civil surfaces (from the borehole levels) of the densities and used the principles in this video https://www.youtube.com/watch?v=WWFZK4IY2g8&feature=youtu.be

There may be a far slicker way just by using vanilla surfaces and solids which may get a better response in the AutoCAD forum

With the free SketchUP you could get something like this:

I never tried it upon exporting vectors from Autocad, but I guess it's quite doable, sir.
