So I have a file for my surface, and another file for doing earthworks calculations in seperate from the main surface file using data shortcuts.
I create a volume surface comparing the existing and proposed sites to come up with cut/fill calculations to display on the final sheet. I go into said sheet, where I have data referenced in the volume surface. Everything is working fine it seems, and then I create a dynamic cut/fill annotation table to display the total cut and total fill (-9m to 0m, 0m to 9m are the two ranges). Now, in the earthworks model file, it shows that the total volume is 115,000m^3 (this volume calculation is all cut). HOWEVER, in the sheet file where the surface is data referenced into, the annotation table shows a volume that is nearly 1/3rd the actual volume. Quick byhand calculations (old school geometry for the win) confirm that the first number is correct. Is Civil 3D losing data in the referencing? This boggles my mind. Any suggestions? Is this a bug, did I do something wrong, or is this just a shortcoming of the software's abilities?
Thanks!
