Hi there,

we do multibeam surveys of the ocean floor, resulting in gridded XYZ files. I would like to print some of our areas via 3D printers (online services?).

In order to produce a waterproof 3D file (STL), I need to add walls and bottom to the 3D surface. I managed to import the data into tools like GeoMapper, Meshlab or AccuTrans3D as STL. However, I'm struggling with adding walls & bottom to make it a waterproof "block". Anyone that has a "how to..." workflow is welcome.

Thanks a lot,
