<br>
Just to see what this method would produce, I installed both Paraview and MeshLab on my Fedora 35 system. I opened a .lox file of the cave in Loch (which displays a 3d rendering of the cave) and then exported it to a .vtk file. I opened the .vtk file in Paraview. It shows nothing. I cannot find the export function. The Save data feature does not offer x3d as a file type.<br>
<br>
In Paraview the Information tab says there are zero cells, zero points and zero memory used. The x-, y- and z-range are "not available".<br>
<br>
The .vtk file exists and is about 16k bytes (it is a small cave).<br>
<br>
Am I missing something?<br>
<br>
