The approximate diameter needs to be in a static field because the list model filters on that field. The filter function is not clever enough to be able to filter on values being in some kind of range or rounded, so instead the decision was made that the rounded value needs to be set in a separate field so that the static filter can filter on it. Contributes to issue CURA-2822.
