save "indexBounds" for e57 files

[perspectivelab]

Hi there !
i would like to sub sample a e57 file which originally has the "indexbounds" node information, unfortunately after the sub sample, i save it again in e57, but it looses the "indexbounds" node while the save. any hints, or this is a feature to be done ?
thank you

I believe the index bounds information is not managed by CloudCompare sadly... So it's 'forgotten' sadly.
