Hello,

I am classifying point clouds using the following command :
" .\CloudCompare -c_export_fmt LAS -ext las -o "micro_cloud.las" -3dmasc_classify "vsimple.txt" "PC1=1" -save_clouds "

The LAS file obtained rearranges the points on lines (see screenshot) :

Do you have an idea why ?
Is there a way to spot the issue or fix the problem ?

Thank you

Yes, that's because with the command line you need to explicitly specify how to manage large coordinates.

You should add

Code: Select all

-GLOBAL_SHIFT AUTO

just after

Code: Select all

-O
