I use a cheap program called DotSoft, XL2CAD.

Very easy to use. Open Excel, do your typing, open Autocad, and start XL2CA program.
Program asks where and scale to insert the spreadsheet into
autocad.
I will be excavating and stockpiling and then rehandling this stockpile of shale. Is there an overall swell or compaction factor available? I will be not be using a normal sheep foot compactor but will use the normal rubber tire wheel traffic from off road trucks.
