As Olly mentioned before, the problem is not in the data - but how therion is compiled under 64bit.
When therion uses routines from img.c to read .3d file, it reads them not correctly => number are so large. This problem has nothing to do with data or survex. Survex reports large ranges, because it recevies wrong information from therion. S. Quoting Philip Balister <philip at balister.org>: > Hmm, you are correct.
