What is the recommended process to mesh a BitArray? The meshing method requires an isovalue. For a BitArray, an isovalue of 1, true or :true don’t seem to work: 0 faces are returned. Another method is to convert from BitArray to an Array: MyData = 1MyData. Then isovalue=0.5 could work. In general…

Your isosurface should follow grid edges between nodes with value 1 which are connected nodes with value 0. Since marching cubes doesn’t seem to like this situation where there is no value greater than 1, I would just set iso to some value close to but less than 1, say 0.999 and then round-up all t…
