Thanks. I did this steps to calculate the volume: 1) Export the lox file to vtk format 2) With Paraview software I opened the file vtk 3) I Saved the file as .x3d 4) I opened the file x3d in Meshlab software 6) I applied the filter: Filters -> Quality measure and computation -> compute geometric Measures 7) I opened log window: View -> Show Layer dialog 8) I read the lines Volume Mesh and Mesh Surface Are correct steps. I think it's an interesting process. Bye Filippo On 21/01/2015 10:26, Bruce wrote:

Hello, I would like calculating volume of a cave. I made the survey and I exported with therion loch the file in .vtk. I'm using paraview now, it's a good software for modelling of a solid 3d but I don't found a simple solution to resolve my problem. Have you ever done this calculation? And how? Thanks
