Hi Nick, The calculation of volumens can be done in VM ! Do the following: 1. Create the grid with all your height data 2. Create another grid that covers the same area as the previos. This grid's values should be Z-value where you want the surface to be. Groundlevel or watersurface... 3. Now you'll have to calculate the diffence between these two grid, use the grid calculator. 4. Allmost last thing. Draw a area that show the area you would like to have the volumen calculated for. 5. VM has some tools where you can get updated columns with some values from the grid. One of these should give you the possibility to update with the volumen. I hope this helps you further even thought my desciption is a bit 'inaccuracy'. My VM was removed from my computer when I uninstalled a older version of MapInfo. Happe new year to you all !

I.e. from X,Y and Z data - the way you think Vertical Mapper could but doesn't. A client has VM but wants volume calculations without involving an export to a CAD system. Any ideas??
