Sometimes there is no cutting at all and sometimes it occurs far from the manually drawn cut line, and I can’t figure out the cause or a pattern of when/why this happens. Has anyone experienced the same and found a solution to this issue? I’m using Vision4D 2.12.3 x64 on Win10. Thanks, Esteban |

In larger structures, this tends to work as expected, but it can produce unexpected results in smaller structures - in some cases those structures will not exist. I'm not specifically aware of a bug, but it could an issue related to the now very old version 2.12.3 (released in 10-Oct-2016) . Please send me your dongle number directly, so I can verify upgrade eligibility, to see what other version you could run. We have had numerous releases since then (current release version is 3.1.3), and function has definitely been improved since 2.12.3.

We pinned the splitting problem down to images that were cropped and resampled within Vision4D (prior to surface creation). Therefore we reasoned that exporting to TIFF would abandon any bugs/glitches in the SIS file resulting from the resampling. Indeed exporting the resampled data to TIFF and importing back into Vision4D fixed the surface splitting problem! Surfaces are split as easily and nicely in our resampled images as in full-resolution images. I'll contact you offline fo upgrade options as you suggested.
