in this video I use a Survey data for calculating the volume of Stock Pile volume, for this purpose surveyor take 1st perimeter of Stockpile and lastly he takes the top of stockpile level and coordinates then I make a 2 surface one base surface another top surface for comparison then Autocad Civil 3d give me a volume of Stack pile
for make base surface I used perimeter as a feature line and for comparison surface I used all data of stockpile top and bottom.
hope I clear my topic if any question regarding my this video or other let me know below in comments
take care of your self and others
